Operating States On–Line On–line refers to the printing state. When the printer is on–line, it is ready to receive data and control commands from the host computer, and it prints the data immediately. The message display on the operator control panel displays “On–Line.” The printer must be on–line to receive data from the host computer. Off–Line Off–line refers to the non–printing state.
The Operator Control Panel The operator control panel is at the front of the printer. (See Figure 3–2.) With the printer cover closed, the status lamps, message display, and four switches governing normal printer operation are accessible. With the printer cover raised, eight more switches are accessible. The eight additional switches are used to set printer operating parameters, run self tests, and set paper position. You also use the operator control panel to clear a fault condition and resume printing.

Printer Configuration IMPORTANT Configuration directly affects printer operation. Do not change the configuration of your printer until you are thoroughly familiar with the procedures in this chapter. Configuration refers to the operating properties that define how the printer responds to signals and commands received from the host computer. These properties, the configuration parameters, are set to match the operating characteristics of the host computer system.

Configuration Procedure Use the following procedure to configure the printer from the control panel: 1. Obtain a configuration printout (page 4–2). 2. Determine the parameter values that must be changed to meet your requirements. The Configuration Diagram (page 4–8) shows all menus and parameter values. 3. Take the printer off–line by pressing the ON LINE switch. Open the printer cover. NOTE: The ENTER switch must be unlocked to change a configuration value.
11. Close the printer cover. 12. Press the ON LINE switch to place the printer on–line. Your selected values are now active and will remain set as long the printer is not reset or cleared. Saving Configuration Values When you save a set of configuration values they become the power–up default configuration. To save a set of configuration values: 1. If the printer is on–line, press the ON LINE switch to take it off–line. “Off–line Emulation” appears on the message display. 2. Open the printer cover. 3.
Loading Configuration Values Configuration values saved using the Save Config menu (page 4–5) become the power–up default configuration. Although the factory settings remain permanently stored in printer memory, they are overridden by the last set of configuration values saved. The Load Config menu then gives you the choice of loading either the saved or the factory configuration values. NOTE: If you have not saved a set of configuration values, this procedure loads the factory value set.
Changing Printer Emulations Emulation refers to the ability of the LG06 and LG12 to execute the commands of a Digital printer, an IBM Proprinter III XL, or an Epson FX 850/1050 series printer. The Digital emulation is the default mode when the printer power is turned on, but you can select Proprinter or Epson emulations at any time. To change printer emulations: 1. If the printer is on–line, press the ON LINE switch to place it in the off–line state. “Off–line Emulation” appears on the message display. 2.

Printer Interfaces The printer interface is the point where the data line from the host computer plugs into the printer. The interface processes all communications signals and data to and from the host computer. It consists of a printed circuit board assembly (PCBA) and a connector for the data cable from the host computer. IMPORTANT The LG06 and LG12 are equipped with two parallel interfaces and one serial interface.
Dataproducts Parallel Interface The Dataproducts parallel interface allows the printer to operate with a 50–pin AMP Ampilite HDH–20 male data cable connector. The length of the data cable from the host computer to the printer must be no longer than 30 feet.

Some application programs may require a unique configuration. If the printer is not working properly in the configuration you selected, contact your authorized service representative.
Terminating Resistors For parallel interface configurations, the LG06 and LG12 printers are equipped with 470 ohm pull–up terminating resistors, located at 12C on the Common Controller Board (CCB) and 1K ohm pull–down terminating resistors at location 12D. These are suitable for most applications. If the standard terminating resistor pack is not compatible with the particular interface driver requirements of the host computer, other values of pull–up and pull–down resistors may be required.
EIA–232D Serial Interface The EIA–232D serial interface enables the printer to operate with bit serial devices compatible with an EIA–232D controller. The interface circuit characteristics are compatible with the Electronic Industry Association Specification EIA–232D. Input serial data transfer rates of 150, 300, 600, 1200, 2400, 4800, 9600, or 19,200 baud are selectable at the control panel. The input format consists of a single start bit, 7 or 8 data bits, and one or two stop bits.

Routine Service Periodic cleaning is the only maintenance your printer requires. If print quality deteriorates even after cleaning, contact your authorized service representative. Cleaning Requirements Periodic cleaning ensures efficient operation and clear print quality. Clean the printer every six months or after every 1000 hours of operation, whichever occurs first. If the printer is located in a dusty area or is used for heavy duty printing, clean it more often.
Exterior Cleaning Clean the outside of the cabinet with a soft, lint–free cloth and mild detergent soap. (Dishwashing liquid works well.) Do not use abrasive powders or chemical solvents. Clean the windows with plain water or mild window cleaner. Always apply the cleaning solution to the cloth; never pour cleaning solution directly onto the printer. Interior Cleaning Over time, particles of paper and ink accumulate inside impact printers. This is normal.
5. Using a soft–bristled brush and vacuum cleaner, brush and vacuum paper and dust particles from the paper path, ribbon guides, ribbon path, and base pan. 6. Check the ribbon mask and hammer bank cover for bits of torn paper or ribbon lint. Check the holes in the ribbon mask surrounding each hammer tip. Gently remove paper or lint particles with a wooden stick or pair of tweezers. (Do not pry or apply force to the hammer tips.) 7.

Printer Self–Tests Run the printer self–tests to check the print quality and operation of your printer. The self–tests include: • ASCII Swirl – A sliding alphanumeric pattern that identifies missing or malformed characters, improper vertical alignment, or vertical compression. • All Es – A pattern of all uppercase letter Es that identifies missing characters, misplaced dots, smeared characters, improper phasing problems, or light/dark character variations.
Running the Self Tests To run the self–tests: 1. On the control panel, press the ON LINE switch to place the printer off–line. “Off–line/Emulation” displays. 2. Raise the printer cover. 3. On the control panel, press the DOWN switch. “Emulation/LG06” displays. 4. Press the NEXT switch until “Emulation/Self Test” displays. 5. Press UP and DOWN simultaneously to unlock the panel. “Unlocked” briefly displays. (If “Locked” displays, simply press UP and DOWN again.) 6. Press ENTER.
Hex Code Printout A hex code printout (or hex dump) is basically a translation of all host interface data to its hexadecimal equivalent. A hex dump lists all ASCII character data received from the host computer with their corresponding two–digit hexadecimal codes. Hex dumps are used to troubleshoot printer data reception problems. Printable characters print as the assigned symbol; nonprintable characters are indicated by a period (.). To make a hex printout: 1. Press ON LINE to place the printer off–line.
Fault Messages If a fault condition occurs in the printer, the status lamps on the message display flash on and off and the first line of the display indicates “Fault Condition.” The second line of the display indicates the specific fault.

Digital Emulation Emulation refers to the ability of a printer to execute the commands of other printer control languages. Digital emulation mode (displayed as “LG06” on the control panel) enables the LG06 and LG12 to print files coded for a Digital LG02 printer. Digital emulation is the default mode when the printer is turned on. A printer control language (also called a printer protocol) is the coding system used to convey, manipulate, and print data. It contains character codes and command sequences.
8. Press UP and DOWN simultaneously to lock the ENTER switch. “Locked” appears briefly on the message display. 9. Close the printer cover. 10. Press the ON LINE switch to place the printer on–line to the host computer. Bar Code Printing Bar code printing is selected by control sequences, not via the operator control panel. Bar code printing is covered in Appendix A.
If word length is 7–bits, printable characters are only generated from columns 2 through 7. If word length is set at 8–bits, printable characters can be generated from columns 2 through 7 and columns 10 through 15. (Note that in an 8–bit environment, columns 0 through 7 have the 8th bit set to zero, while columns 8 through 15 always have the 8th bit set to 1.

Control Codes A control code is a single (one byte) non–printing character that instructs the printer to perform a specific operation. When the printer receives a control character, it immediately performs the control operation instead of printing a graphic character.
Table 7–1. ASCII Control Codes Mnemonic Column/Row Name BEL 0/7 HT 0/9 Bell Horizontal Tab Key Pressed with CTRL None I Function When a control code is received, the printer produces a short audible tone. HT advances the active tab position to the next horizontal tab stop on the line, or to the right margin if there are no more tab stops. The printer initially sets a horizontal tab stop every eight characters.
Table 7–1. ASCII Control Codes (Continued) Mnemonic Column/Row CAN 1/8 Name Key Pressed with CTRL Cancel X Function CAN immediately ends an escape or control sequence. The printer interprets the characters following CAN as normal. CAN also cancels a Device Control String (DCS) when received within the command string of that DCS. 7–8 SUB 1/10 Substitute Z SUB immediately ends an escape or control sequence. SUB replaces a character received with an error in the sequence.
Table 7–2. Additional Control Codes Mnemonic Column/Row Name Function IND 8/4 Index IND moves the active position down to the same position on the next line. If the new position is below the bottom margin, the active position moves to the top of the next page. NEL 8/5 Next Line NEL moves the active position to the left margin on the next line. If the new position is below the bottom margin, the active position moves to the top of the nex page.
Table 7–3.
8–Bit to 7–Bit Control Code Conversion Convert 8–bit additional control codes to 7–bit escape sequences as follows: 1. Insert the ESC character. 2. Set the eighth bit of the final character to 0 and set its seventh bit to 1. NOTE: Only control codes found in columns 8 and 9 of the character sets may be converted as shown. Printable characters in columns 10 through 15 are not converted. 7–Bit to 8–Bit Control Code Conversion Convert 7–bit escape sequences to 8–bit additional control codes as follows: 1.
Escape Codes The control codes discussed in the previous section are single byte control codes. The number of printer capabilities is greatly increased, however, by combining character codes into escape sequences. Escape sequences always begin with the ASCII ESCape character (location 1/11). An ESC character in the data stream signals the printer to wait for special instructions. The character codes following the ESC character tell the printer what to do.
always comes from the 3/0 through 7/14 range of the DEC multinational character set. For example, if the intermediate character is SP (hex 20) and the final character is G (hex 47), the resulting escape sequence is ESC SP G (hex 1B 20 47). This particular sequence tells the printer how to process data it sends back to the host computer: send data in 7–bit form and send additional control characters as 7–bit escape sequences.
Parameters are interpreted as unsigned decimal integers with the most significant digit first. Parameter values greater than the maximum allowable 65535 will be set to 65535. Do not use a decimal point in any parameter — the printer will ignore the entire command. If no value is specified, zero (0) is assumed. A value of zero or an omitted parameter indicates the printer default value should be used for that sequence.
Special Parsing Requirements Parsing is the process of separating a programming statement into basic units that can be translated into machine instructions. Special parsing requirements are necessary when invalid parameters are specified, when invalid control functions are specified, and when control characters are embedded in control functions. Generally, the printer recovers from these conditions by performing as much of the function as possible (or, parsing the valid parameter from the invalid).
When the characters (20H) or (7FH) are received after a SS2 or SS3, the following occurs: • If the (94) character set resides in the set being accessed (either G2 or G3), the or keys are processed and the single shift flag remains set. • If the (94) character set resides in the set being accessed (either G2 or G3), the printer images the corresponding character of that set (A0H or FFH), then reset the single shift flag.
If either (A0H) or (FFH) are received after SS2 or SS3, the following occurs: • The LG06 and LG12 print the error character (a reverse question mark) and resets the single shift flag when a (94) character resides in the set being accessed (either G2 or G3). • If a (96) character resides in the set being accessed (either G2 or G3), the printer images the corresponding character, (A0H) or (FFH), of that set, then resets the single shift flag.
Control Code Index and Descriptions The Digital emulation mode control codes listed below are grouped by related functions. Control code sequences in this manual are shown in 7–bit form. They can be either 7–bit or 8–bit form, depending on your requirements. Code conversion instructions are on page 7–11. For commands that turn features on and off (set/reset, enable/disable), the page number for the enabling command is listed. The disabling command is on the same page.

Discussion Pn is a decimal value that species the height of the font in units determined by the Select Size Unit (SSU) sequence. The width of the font is implicitly defined by the height. For example, the width of a 10–point font is 10 pitch. The initial value for Pn is Pn = 100.
Graphic Size Modification (GSM) ASCII Code ESC [ Pn1 ; Pn2 SP B Hex Code 1B 5B Pn1 3B Pn2 20 42 Dec Code 27 91 Pn1 59 Pn2 32 66 Purpose Modifies the height and width for all designated fonts as set by the GSS sequence. Discussion Pn1 is a decimal value that specifies the height of the font as a percentage of the height set by the GSS sequence. Pn2 is a decimal value that specifies the width as a percentage of the width set by the GSS sequence.
Setting Plot Density The printer can plot in several different densities (dots per inch), from 30 dots per inch to 200 dpi. The Plot mode fonts contain the information for the vertical and horizontal densities they use. Determine non–text imaging densities (for sixels, bar codes) by using these innate commands. Default values for both the vertical and horizontal densities for graphic work are 100.
Set Graphics Density (DECSGD) ASCII Code ESC [ Psh ; Psv & { Hex Code 1B 5B Psh 3B Psv 26 7B Dec Code 27 91 Psh 59 Psv 38 123 Purpose Sets the darkness of drawn images. Discussion DECSGD controls darkness via the density of the physical pixels. It does not change the resolution of the image (logical pixels), only the darkness of the segments drawn. NOTE: Psh and Psv do not affect the density of plotted text. Text density comes from the current font.

Spacing The five spacing sequences covered in this section affect the spacing of lines and characters on the page but do not affect character size. Horizontal pitch affects character spacing in characters per inch (cpi). Vertical pitch affects line spacing in lines per inch (lpi). Table 7–9. Line and Character Spacing Sequences Sequence Name DEC Mnemonic Page No.
Spacing Pitch Increment (SPI) ASCII Code ESC [ Pn1 ; Hex Code 1B 5B Pn1 3B Pn2 20 47 Dec Code 27 91 Pn1 59 Pn2 32 71 Purpose Sets the vertical and horizontal spacing increments for all characters that follow in the data stream. You can select one or both increments with a single Spacing Pitch Increment sequence. The SPI sequence gives you the greatest flexibility in adjusting white space (pitch) between characters and lines. Discussion This command sequence uses decipoints or pixels as units.
Spacing Pitch Increment (SPI) (continued) If a position command does not precede the printable (graphic) character, the printer will place that character to the right of the previously received character. The distance between characters depends on the values of Pn1 and Pn2 in the most recent SPI, SHS, or DECSHORP sequence. If you set the Pn1 or Pn2 values to 0, or if you do not send an SPI sequence, the printer uses the default horizontal and vertical spacing for the font currently in use.
Set Vertical Pitch (DECVERP) ASCII Code ESC [ Ps z Hex Code 1B 5B Ps 7A Dec Code 27 91 Ps 122 Purpose Selects the number of lines printed per inch on the page. Discussion Selects the line spacing (vertical pitch) used with all fonts. Ps selects the vertical pitch (lines per inch). Ps Vertical Pitch 0 6 lines per inch (current default) 2 8 lines per inch 7 10 inches per line (This setting is accomplished by reversing the paper.
Select Horizontal (Character) Spacing (SHS) ASCII Code ESC [ Ps SP K Hex Code 1B 5B Ps 20 4B Dec Code 27 91 Ps 32 75 Purpose Selects character spacing (horizontal pitch). Discussion Ps selects the horizontal pitch and the horizontal character position unit. By setting this parameter, the white space between characters varies, but the character size is not affected.
Set Horizontal Pitch (DECSHORP) ASCII Code ESC [ Ps w Hex Code 1B 5B Ps 77 Dec Code 27 91 Ps 119 Purpose Selects the character spacing for monospaced fonts. This sequence selects the number of characters printed per horizontal inch on a line. NOTE: DECSHORP varies the white space between characters, not the actual character size. Discussion Pitch Select Mode (DECPSM) activates the Set Horizontal Pitch (DECSHORP) sequence.
Vertical Format Vertical format consists of two control codes that program the printer to make fast vertical paper movements (slewing) during print jobs. Vertical formatting increases printer efficiency and reduces printing time for repetitive printing jobs. Vertical channels in the form are defined by downloading the Vertical Format Unit (VFU) from the host to the printer. Subsequent data is then printed on the form at the specified channel. These functions are achieved by using control sequences.
Load Vertical Format Unit (VFU) ASCII Code ESC [ < 1 h Hex Code 1B 5B 3C 31 68 Dec Code 27 91 60 49 104 Purpose Downloads the VFU from the host to the printer. Discussion All data following the begin load sequence is placed in VFU memory except ASCII control codes. Any command entered during load VFU is ignored except the End Load sequence. During VFU load, a unique code is displayed on the control panel. All data must be in the VFU load format.
Load Vertical Format Unit (VFU) (continued) Table 7–11. Byte 2 Structure (Second Character of Pair) Bits: 7 6 5 4 3 2 1 0 Values: x 1 C12 C11 C10 C9 C8 C7 The following define the values in Table 7–11: C1 – C12 are channels 1 through 12. C1 identifies top–of–form (TOF). C12 identifies bottom–of–form (BOF). End Load (VFU) ASCII Code ESC [ < 1 l Hex Code 1B 5B 3C 31 6C Dec Code 27 91 60 49 108 Purpose Ends the Vertical Format Unit load.
Channel Command ASCII Code ESC [ nnn & y Hex Code 1B 5B nnn 26 79 Dec Code 27 91 nnn 38 121 Purpose The channel commands control paper motion. nnn is the channel number. When the first n equals 0, forward paper motion occurs. When the first n equals 9, reverse paper motion occurs. If the first n equals any value other than 0 or 9, the entire sequence is ignored. Table 7–12 gives the values of nnn for each channel. Table 7–12.
Channel Command (continued) • If a VFU table is not loaded and channel commands are sent to it, a line feed occurs then the text prints. • If you load a VFU table with more than one TOF and/or more than one BOF already defined, the load is terminated and a warning message is displayed on the front panel.
Forms A form contains data. This data is a sequence of self–contained commands and text that can occupy one or more pages of the form. The data form can be downloaded then stored in printer memory for later use. The status report lists the form IDs loaded in the printer. Once a form is downloaded, it is selectable. Stored data is merged with the fill–in data stream, and the merged data is printed as a completed form.
Loading Forms Sequence (DECLFM) ASCII Code DCS P1 ; P2 & p RECORD ST Hex Code 90 P1 3B P2 26 70 RECORD 9C Dec Code 144 P1 59 P2 38 112 RECORD 156 Purpose Allows you to load forms into printer memory. Discussion The Pn parameters define the format of the form as well as which forms to delete. Forms can be loaded at any time except during another download operation, or while a form is printing.
Loading Forms Sequence (DECLFM) (continued) The form record includes a form header that defines form parameters and size, and the form data string. This information is contained in the format header and includes: • ID length is a two digit number (01 – 99) that defines the length of the form ID. • Form ID is a string of 1 – 99 printable characters. IDs exceeding 10 characters are truncated. The control–character encoding character indicates the start of control–character encoding.
Loading Forms Sequence (DECLFM) (continued) • Form Data Switch Character designates the insertion of the form’s fill–in data. The character, considered a field indicator character, is always in a range from 2/0 through 7/14. The form–data switch character must be different from the control–character encoding character. The form data switch character is not printable within the form and should not be used in any control sequence in the form.
Form Types A form can be printed in Print mode, in Plot mode, or in a combination of Print and Plot mode. • In Plot mode, all positioning should be fully specified by the Digital positioning commands. The entire form is plotted if the following conditions exist: Contains any graphics (block characters, bar codes, vectors, logos) The pitch of the font does not exist in print mode The form uses justified text • In Print mode, all positioning is controlled by the CR, LF, and tabs control characters.
Start Forms Sequence (DECIFM) ASCII Code DCS P1 & r FORM NAME ST Hex Code 90 P1 26 72 FORM NAME 9C Dec Code 144 P1 38 114 FORM NAME 156 Purpose Selects any form loaded in RAM. Discussion P1 is the Select Form Switch character. With this sequence, a form loaded in RAM is selectable for printing. When you select the form, the printer enters Form mode. The variable fill–in data is merged and printed with the form data.
Terminate Forms Sequence (DECTFM) ASCII Code ESC # SP 1 Hex Code 1B 23 20 31 Dec Code 27 35 32 49 Purpose Terminates the printing of a form. Discussion If no form is selected, this sequence is ignored. Many special conditions might affect the printer output or performance in its various uses. See “Forms Considerations,” page 7–55, for further information regarding these conditions.
Forms Considerations The following commands are not to be included in form data or fill–in data: • Load a form, logo, or font • Delete a form, logo, or font • Invoke a Digital sequence • Invoke a ESCc (RIS) sequence. This will exit you from the Form mode. Be aware of the following conditions, which can affect the printer’s output/performance in Forms mode: • To minimize paper movement, print all text together and print all graphics together.
Forms Considerations (continued) When using bar codes, note the following: • When using bar codes as part of the form data, make sure that the control character encoding character in the bar code differs from the control character encoding character and the switch character in the Loading Form sequence. • When using bar codes as part of the fill–in data, make sure that the control character encoding character of the bar code differs from the switch character in the Select Form sequence.
Logos A logo is a graphic image stored in the printer. Once a logo is downloaded, it can be printed repeatedly by referring to its identifying number. Up to 16 logos can reside in the printer, with a maximum size of 65,000 bytes per logo. The following subsections explain various ways in which to utilize the logo feature. Loading Logos Sequence (DECLLG) ASCII Code DCS P1 ; P2 & t RECORD ST Hex Code 90 P1 3B P2 26 74 RECORD Dec Code 144 P1 59 P2 38 116 RECORD Purpose Loads logos into printer memory.
Loading Logos Sequence (DECLLG) (continued) The logo record includes all data after the final character (t) and up to the string terminator, as well as the logo header portion and the row data strings portion. The logo header contents identify the logo and the size (number of characters) of the row data string. The logo record variables include: • ID Length is a one digit number (1 through 4) that defines the length of the logo ID. • Logo ID is a string of one to four numerals that identify the log.
Select Logo Sequence (DECILG) ASCII Code CSI Pn & } Hex Code 9B Pn 26 7D Dec Code 155 Pn 38 125 Purpose Prints selected logos present in printer memory. Discussion Pn defines the ID of the selected logo. If no logo exists for that ID, the sequence is ignored. Logos are printed in the current page orientation and graphics density. Before you select a logo sequence, set the logo density with DECSGD and the orientation. When the logo sequence is complete, reset the density and the cursor position.
Deleting Logos Sequence (DECDLG) ASCII Code CSI P1 ; P2 ; ... ; Pn & | Hex Code 9B P1 3B P2 3B 2E2E2E 3B Dec Code 155 P1 59 P2 59 464646 59 Purpose Deletes logos from printer memory. Discussion P1 defines the logos to be deleted: P1 Function 0 3 Delete all logos whose IDs are listed Delete all stored logos When P1 = 0, parameters P2 through P16 make up the ID of the logos to be deleted. You can select up to 16 logo IDs to delete. Deleting a logo within a form is not allowed.
Logo Status Report (DECLGSR) ASCII Code DCS & w LOGO STRING ST Hex Code 90 26 77 LOGO STRING 9C Dec Code 144 38 119 LOGO STRING 156 Purpose Reports the logo status in response to the DECRLGR sequence. Discussion The logo string contains a list of all the valid logos loaded in the printer and their comment strings.
Page Print Area and Margins The LG06 and LG12 have no print area limitations; however, smaller page areas can be selected by using the Page Format Select (PFS) sequence. Figure 7–1 shows the two types of page orientation: portrait and landscape.
Page Print Area and Margins (continued) Changing the Print Area You can change the print area two ways: 1. Set the printed page to one of the predefined formats using the Page Format Select (PFS) sequence (see page 7–64). PFS permits you to set page format with one command. 2. Change the page margins and the number of lines per page with these sequences: d. Set Lines Per Physical Page (DECSLPP) e. Set Top and Bottom Margins (DECSTBM) f.
Page Format Select (PFS) ASCII Code ESC [ Ps SP J Hex Code 1B 5B Ps 20 4A Dec Code 27 91 Ps 32 74 Purpose Selects a page format from a list of predefined formats. Discussion Ps selects one of 12 page formats. Two kinds of format are available: normal and extended. In the normal page format, the page home line is 0.5 inches below the top margin, and the page end line is 0.833 (5/6) inches above the bottom margin.
Page Format Select (PFS) (continued) The page home line is the active line after a form feed (FF). The index (IND), next line (NL), and carriage return characters cause a form feed when they pass the page end line. Use the vertical position absolute and relative (VPA and VPR) sequences to move below the page end line. If a line feed passes the page end line, the printer prints the current page and performs a form feed to get to the next page.
Page Format Select (PFS) (continued) Table 7–14 shows the lines per page and the characters per line selected with the normal and extended PFS formats. Table 7–14. Lines Per Page and Characters Per Line Using PFS Formats Ps Format Description Lines Per Page in Text Area (Lines Per Inch) 8 6 4 3 Chars.

Set Lines Per Physical Page (DECSLPP) ASCII Code ESC [ Pn t Hex Code 1B 5B Pn 74 Dec Code 27 91 Pn 116 Purpose Defines form length. Discussion A form’s length equals the maximum distance the paper moves when a form feed command is issued. Maximum form length is 33 inches. DECSLPP sets the top margin to 1 and the bottom margin to the form length. Form length limits the range of possible settings for the Set Top and Bottom Margins (DECSTBM) sequence.
Set Top and Bottom Margins (DECSTBM) ASCII Code ESC [ Pn1 ; Hex Code 1B 5B Pn1 3B Pn2 72 Dec Code 27 91 Pn1 59 Pn2 114 Purpose Sets the top and bottom margins, and the page home line. These settings are relative to the current origin point for page coordinates. (Refer to “Page Format Select” on page 7–64.) Discussion Pn1 sets the top margin and the page home line. Pn2 sets the bottom margin. If the first parameter is greater than the second parameter, the printer will ignore the sequence.
Set Left and Right Margins (DECSLRM) ASCII Code ESC [ Pn1 ; Hex Code 1B 5B Pn1 3B Pn2 73 Dec Code 27 91 Pn1 59 Pn2 115 Purpose Sets the left and right margins. Discussion Pn1 sets the left margin and the line home position. Pn2 sets the right margin. If the first parameter is greater than the second parameter, the printer will ignore the sequence. The unit of measurement can be character cells, decipoints, or pixels.
Set Left and Right Margins (DECSLRM) (continued) • If Autowrap is enabled and the active position is grater than the specified right margin, the next printable character causes a carriage return/line feed before the next character is printed. If Autowrap is disabled (truncated), the characters that follow this command are ignored until the cursor is returned to the printable area.
Active Column and Active Line (Cursor Motion) This section describes cursor positioning command sequences. Line printers do not have a cursor like the blinking place–marker on most computer screens. The cursor position on a line printer is the space where the next character will print. In this manual, cursor refers to the currently active print position. Its location is the intersection of the active column and active line.
Reverse Index (RI) ASCII Code ESC M Hex Code 1B 4D Dec Code 27 77 Purpose Causes the active position to move to the corresponding character position of the preceding line. Discussion Pn specifies the active position. The Reverse Index command causes the active position to stop at the top of the margin. In 8–bit mode, the Reverse Index 8–bit control code can be used for this function (refer to “Control Characters,” page 7–6).
Horizontal Position Absolute (HPA) ASCII Code ESC [ Pn ‘ Hex Code 1B 5B Pn 60 Dec Code 27 91 Pn 96 Purpose Selects the active column on the active line. Discussion Pn value specifies the new active column. Default value: Pn = 1. If you try to move the active column to the right of the last position on the line, the active position stops at the last position on the line.
Horizontal Position Backward (HPB) ASCII Code ESC [ Pn j Hex Code 1B 5B Pn 6A Dec Code 27 91 Pn 106 Purpose Moves the active column backward by subtracting the value Pn from the currently active column. Discussion Pn is the value subtracted from the currently active column. Default value: Pn = 1. If you try to move the active column to the left of the first position on a line, the active position stops at the first position on that line.
Vertical Position Relative (VPR) ASCII Code ESC [ Pn e Hex Code 1B 5B Pn 65 Dec Code 27 91 Pn 101 Purpose Moves the active line to the corresponding horizontal position by adding Pn the value to the currently active line. Discussion Pn is the value added to the currently active line. Default value: Pn = 1. If you try to move the active line below the bottom line, the active position stops at the bottom line.
Cursor Up (CUU) ASCII Code ESC [ Pn A Hex Code 1B 5B Pn 41 Dec Code 27 91 Pn 65 Purpose Causes the active position to move to the corresponding column at the preceding vertical position set by the Pn value. Discussion If you try to move the active position above the top line, the active position stops at the top line. Pn is the number of lines that the active line moves up at the current active column. Default value: Pn = 1.
Partial Line Up (PLU) — Superscripting ASCII Code ESC L Hex Code 1B 4C Dec Code 27 76 Purpose Print superscripted characters. Discussion This sequence moves the active position up a distance equal to 1/2 a vertical line increment, as determined by the currently active font. The Partial Line Down (PLD) sequence returns the active position to the previous baseline.
Partial Line Down (PLD) — Subscripting ASCII Code ESC K Hex Code 1B 4B Dec Code 27 75 Purpose Print subscripted characters. Discussion This sequence moves the active position down a distance equal to 1/2 a vertical line increment, as determined by the currently active font. The Partial Line Up (PLU) sequence returns the active position to the previous baseline.
Tab Stops A tab stop is a predetermined point to which the active position moves when you send the HT and VT tab commands. The active position is where the next character will print. A page can have a maximum of 32 horizontal tabs, and a maximum of 67 vertical tabs. You can set horizontal and vertical tabs. The printer will ignore tab setting commands for tabs already set. Likewise, the printer will ignore tab clearing commands for tabs already cleared.
Set Horizontal Tab Stops (DECSHTS) ASCII Code ESC [ Pn ; Hex Code 1B 5B Pn 3B ... 3B Pn 75 Dec Code 27 91 Pn 59 ... 59 Pn 117 Purpose Pn denotes a horizontal tab stop location. Discussion DECSHTS allows you to select up to 16 horizontal tab stops at one time. Thirty–two possible horizontal tab stops are available, however, any sequence beyond 16 is ignored. The Pn values can be in any order in the escape sequence. ... ; Pn u The unit of measurement can be character cells, decipoints, or pixels.
Set Horizontal Tab Stops (HTS) ASCII Code ESC H Hex Code 1B 48 Dec Code 27 72 Purpose Causes a horizontal tab stop to be set at the current position. Discussion A horizontal tab stop can also be achieved in 8–bit mode by sending the HTS 8–bit control code. Set Vertical Tab Stops (DECSVTS) ASCII Code ESC [ Pn ; Hex Code 1B 5B Pn 3B ... 3B Pn 76 Dec Code 27 91 Pn 59 ... 59 Pn 118 Purpose Sets vertical tabs at the rows indicated. Discussion Pn denotes a vertical tab stop location.
Set Vertical Tab Stops (VTS) ASCII Code ESC J Hex Code 1B 4A Dec Code 27 74 Purpose Causes a vertical tab stop to be set at the current position. Discussion A vertical tab stop can also be achieved in 8–bit mode by sending the HTS 8–bit control code. Tab Clear (TBC) ASCII Code ESC [ Ps g Hex Code 1B 5B Ps 67 Dec Code 27 91 Ps 103 Purpose Clear one or all horizontal or vertical tab stops. Discussion Ps selects which tab stops to clear.
Soft Terminal Reset (DECSTR) ASCII Code ESC [ ! p Hex Code 1B 5B 21 70 Dec Code 27 91 33 112 Purpose Resets the value or state of several operating features. Discussion After receiving a DECSTR, the printer positions itself at the next top of form, then resets the value or state of several operating features. Additionally, this command resets any event not reported in a Device Status Report (see “Device Status Reports,” page 7–89 ).
Character Set Selection To make a character set available for printing, you must designate the set as either G0, G1, G2, or G3. The designated set is then invoked into GL or GR using single or locking shift, and can be used for printing. National Replacement Characters (NRCs) are created by replacing the relevant characters in the U.S. ASCII character set upon receipt of the appropriate control sequences.
Select Character Set Sequences (SCS) The Select Character Set Sequence (SCS) assigns a character set to the G0, G1, G2, or G3 character set designators. Table 7–17 give the sequences that select the available language sets. Table 7–17. Selecting Language Sets Using Single and Locking Shifts Character Set G0 G1 G2 G3 U. S.
Product Identification (DA) ASCII Code ESC [ c Hex Code 1B 5B 63 1B 5B 30 63 Dec Code 27 91 99 27 91 48 99 Purpose Shows the product identification. Discussion When the host computer sends a device attributes (DA) sequence, the printer immediately sends an answering sequence that identifies the printer.
Printer Status Requests and Reports The host computer can send Device Status Requests (DSRs) to the printer, which will then respond with status reports about its operational condition. The printer will send brief or extended and solicited or unsolicited reports to the host. Unsolicited status reports are sent only when an error occurs and only when unsolicited status reports are specifically enabled. Unsolicited status reports are sent after the current page prints, and list each error type once.
Device Status Requests (DSRs) (continued) Printer Status Reports The printer sends a Device Status Report (DSR) to the host via the serial line when requested by the host (DSR) or when unsolicited reports have been previously enabled and a reportable status condition has occurred. The host can request a brief or extended status report, as follows: NOTE: The question mark (?) character occurs only once per DSR sequence.
Device Status Requests (DSRs) (continued) Request Sequence CSI Pn1 ; Pn2 R Cursor Position Report Pn1 is the active line Pn2 is the active column Values of Pn (up to three digits) are defined in Table 7–18. Printer status codes are reported in pairs: a generic error code first, then a specific error code. A hardware failure consists of any errors listed in “Self–test error messages” and “Font Checksum Errors found at Initialization.” 7–90 1.
Device Status Requests (DSRs) (continued) Table 7–18.

Assigning and Selecting Font Files Each font file stored in printer ROM includes data for one of the three standard character sets: ASCII, DEC Supplemental, and DEC Technical. Each font file also includes data for one font, which is part of a type family. You can identify font files by type family ID, font ID, and font file ID. (Refer to Appendix E.) The type family ID consists of seven characters. The type family IDs for the standard type families used with ROM–resident font files are listed below.
Assign Type Family or Font (DECATFF) ASCII Code DCS Ps1 ; Ps2 } ID String ST Hex Code 90 Ps1 3B Ps2 7D ID String 9C Dec Code 144 Ps1 59 Ps2 125 ID String 156 Purpose Assigns a GSR number to a font ID or type family ID. Discussion To select fonts for printing or plotting graphics, you must assign a Select Graphic Rendition (SGR) number to the type family ID (seven characters) or font ID (16 characters). Each font file contains an ID string as part of its font record.
Assign Type Family or Font (DECATFF) (continued) Ps2 Parameter Ps2 selects the SGR number to assign to the type family ID or font ID.
Selecting Fonts for Printing (SGR) ASCII Code CSI Ps m Hex Code 9B Ps 6D Dec Code 155 Ps 109 Purpose Selects fonts for printing or plotting. NOTE: This SGR sequence format is also used to select several character attributes. (Refer to page 7–99.) You can combine several SGR sequences by separating Ps values with semicolons ( ; ). Discussion Ps values from 10 through 19 select the font or type family used for printing. (Initial SGR number assignments are covered on page 7–93.
Deleting Fonts from RAM (DECLFF) ASCII Code DCS 0 ; 1 ; 0 y ST Hex Code 90 30 3B 31 3B 30 79 9C Dec Code 144 48 59 49 59 48 121 156 Purpose Deletes fonts from RAM. Discussion Digital LG printer emulation fonts are in portrait orientation by default. Each time you request a landscape orientation and select a font, the printer creates a rotated font in RAM. The RAM may fill if you create a number of fonts. The following command sequence lets you delete fonts from RAM.
Font Status Sequences Font status sequences help the host computer control and manage font memory. The host sends a request font status sequence, and the printer responds by sending a font status report. The font status report tells the host which fonts are currently available in the printer.
Font Status Report (DECFSR) The printer uses this sequence to report the font status requested by the DECRFS sequence (page 7–97). There is a separate report for the two types of status requests. NOTE: This command works only when the printer is connected to the host through the serial interface.
Character Attributes (SGR) Character attributes are enhancements that let you highlight your printed text. You can select ten character attributes by using Select Graphic Rendition (SGR) sequences: • Select font (DEC multinational character set, NLQ, OCR–A, OCR–B) • Character Expansion via Graphic Size Modification (GSM) sequences (Double height characters, triple height characters, double width characters), if the font was selected by family.
Character Expansion (GSM) ASCII Code ESC [ Ps1 ; n2 SP B Hex Code 1B 5B Ps1 3B Dec Code 27 91 Ps1 109 n2 32 66 Purpose Ps1 multiplies height; n2 multiplies width. Discussion The Character Expansion control sequence allows characters to be multiplied in both height and width. n2 20 42 Multiply Height The printer prints double and triple height characters by expanding the single height character matrix to produce twice or three times the number of vertical dots per character, respectively.
Character Expansion (GSM) (continued) Multiply Width The printer prints double width characters by expanding the single width character matrix to produce twice the number of horizontal dots per character. When double width characters are selected, the Space character also expands to twice the normal width. To double character width, invoke the following cpi: Current Width Pitch (CPI) 10 12 13.3 15 16.7 Double Width (CPI) 5 6 6.6 7.5 8.3 NOTE: The OCR–A and OCR–B fonts cannot be enlarged.
Bold Printing ASCII Code ESC [ Ps m Hex Code 1B 5B Ps 6D Dec Code 27 91 Ps 109 Purpose Turn bold printing on or off. Discussion This sequence causes the printer to print bold text in the same font currently selected. Ps turns bold printing on or off. If the currently selected type family does not have a bold font on the system diskette, the printer will double–strike with a slight offset (“shadow print”) when you turn on bold printing.
Double Underlined Text ASCII Code ESC [ Ps m Hex Code 1B 5B Ps 6D Dec Code 27 91 Ps 109 Purpose Turns double underlining on or off. Discussion With double underlining on, the printer double underlines all following printable characters, including spaces. Double underlining remains in effect (even across page boundaries) until turned off. Note that if you use a tab with double underline enabled, the space is doubly underlined. Ps turns double underlining on or off.
Italic Printing ASCII Code ESC [ Ps m Hex Code 1B 5B Ps 6D Dec Code 27 91 Ps 109 Purpose Turn italic printing on or off. Discussion Text prints in italics only when the Data Processing or Near Letter Quality (NLQ) fonts are in use and italic printing is selected. The values of Ps turn italic printing on or off. The italic font is available at the following cpi’s: 5, 10, 12, 13.3, 15, and 16.7, and at all horizontal pitch settings except 16.7.
Turn Off All Attributes ASCII Code ESC [ 0 m Hex Code 1B 5B 0 6D Dec Code 27 91 0 109 Purpose Turns off all font attributes. Underlined Text ASCII Code ESC [ Ps m Hex Code 1B 5B Ps 6D Dec Code 27 91 Ps 109 Purpose Turn underlining on or off. Discussion With underlining on, the printer underlines all following printable characters, including spaces. Underlining remains in effect (even across page boundaries) until turned off.
Justification (JFY) ASCII Code ESC [ Ps SP F Hex Code 1B 5B Ps 20 46 Dec Code 27 91 Ps 32 70 Purpose Aligns text at left and right margins. Discussion Justification changes the spacing between words. With a justified line, the first character of the first word is flush with the left margin, or at the line home position if it differs from the margin setting. The last character of the line will be at the right margin. Once enabled, justification remains on until you turn it off.
Justification (JFY) (continued) • Vertical Table (VT) • Next Line (NEL) • Forward Index (IND) • Reverse Index (RI) • Vertical Position Absolute (VPA) The active font determines the distance between characters in a word. The printer will not autowrap text with justification turned on; therefore, text that exceeds the printable area is lost. The printer does not justify leading spaces; instead, it uses the default width of the space character (SP).
Sixel Graphics Processing A sixel is a group of six vertical picture elements (six pixels) that represents a section of a graphic image. It can be sent in one byte (7 or 8 bits). A bit value of 1 means print a pixel; a bit value of 0 means leave a space. The sixel protocol is a bit–imaged rasterised method of transmitting and displaying graphic images. The printer receives and prints sixel files sent from the host. These images are printed in monochrome.
The String Introducer Control code (DCS) identifies the start of the sixel protocol. The DCS code is 90H in 8–bit mode. In 7–bit mode, it is 1BH, 50H. Protocol Selector The protocol selector consists of a string of zero, one, or more numeric parameters, each separated by the parameter separator character, ; (semicolon, 3BH). A valid numeric parameter consists of zero, one, or more digits in the range of 30H – 39H. The protocol selector has the following format: ASCII Code Ps1 ; Ps2 ; Pn3 ...
The printer performs default horizontal grid sizes for some decipoint values. The following table identifies the horizontal grid size used for each parameter value. Decipoints (1/720”) Horizontal Grid Size 0 or none No change to HGS defined by Ps1 1, 2, 3 1/180in (.0056 in) 4 5 1/180in (.0056 in) 1/180in (.0056 in) 6 default to: 1/180in (.0056 in) 7 default to: 1/180in (.0056 in) 8 1/180in (.0056 in) 9 default to: 1/180in (.0056 in) 10 1/180in (.0056 in) 11 – 19 default to: 1/180in (.
When the 100:100 aspect ratio is selected by Ps1, Pn3 must take on one of the following values: 1/180 in, change to 200:100 A/R and maintain HGS = 1/180 in 1/140 in, maintain 200:100 A/R and change to HGS = 1/140 in 1/90 in, maintain 200:100 A/R and change to HGS = 1/140 in 1/70 in, maintain 200:100 A/R and HGS = 1/70 in 1/35 in, maintain 200:100 A/R and change to HGS = 1/35 in • Pn is reserved for future use. If parameters are received, they will be ignored without terminating this sequence.
Character Processing in Sixel Graphics Mode In Sixel Graphics mode, characters are made up of standard ASCII text processed as sixel printable characters and sixel control characters. Sixel Printable Characters Sixel printable characters are GL characters in the 3FH – 7EH range decoded as printable characters. Each of these 64 values represent an encoding of six vertical pixels to be printed. The actual pixel size is defined by the Horizontal Grid Size parameter and the pixel aspect ratio.
Sixel Control Codes Sixel control codes are GL characters in the 20H – 3EH range. The parameter separator (3BH) and the parameter digits (30H – 39H) are also included in this range. GR characters in the A0H – BEH range are processed as GL characters by setting the eighth bit to 0. Table 7–20 show how the assigned control characters are processed. Table 7–20.
The numeric parameter specifies the number of times to print the character that follows the repeat introducer. The numeric parameter is a string of characters in the 30H – 39H range, which is evaluated as a decimal number. If a numeric parameter is not received or if the parameter is 0, a value of 1 is assumed. If the parameter is a value larger than the maximum value of 65535, the printer defaults to 65535. All decimal digits are processed as part of the count.
• Pn1 sets the pixel aspect ratio numerator. • Pn2 sets the pixel aspect ratio denominator. Pn1 and Pn2 are numeric parameters. A numeric parameter is a string of characters in the 30H – 39H range that is evaluated by the printer as a decimal number. If the parameter is a value larger than the 65535 maximum, the printer defaults to 65535. The pixel aspect ratio defines the shape of the pixel needed to reproduce the picture without distortion.
When determining pixel size, the printer will attempt to preserve the A/R without exceeding the selected HGS. Therefore, note the following: When 2.5:1 A/R is selected and the HGS is: – 1/180 in, the printer maintains a 2.5:1 A/R and a HGS of 1/180 in – 1/140 in, the printer maintains a 2.5:1 A/R and a HGS of 1/180 in – 1/90 in, the printer maintains a 2.5:1 A/R and changes HGS to 1/90 in – 1/70 in, the printer maintains a 2.5:1 A/R and changes HGS to 1/90 in – 1/35 in, the printer maintains a 2.
printed after entering Sixel Graphics mode. GCR allows sixel data to overprint lines by consecutively starting at the same horizontal position. For example, if the first sixel data prints at column 10, the GCR causes the next line of sixel data to start at column 10 and not at the left margin. Graphic New Line (–) The Graphic New Line (GNL) control code initiates printing, causes the active position to move to the furthest left position, and advances paper by one sixel height.
communication line errors. An ESC character terminates Sixel Graphics mode, but the printer still processes the ESC character. In Sixel Graphics mode, all C1 control codes terminate Sixel Graphics mode, then process the C1 control code if it is recognized by the printer. Graphic Substitute In Sixel Graphics mode, the SUB character is interpreted as an error character. The printer remains in Sixel Graphics mode and processes SUB as a sixel space (3FH).
Processing Unused Control Strings The printer ignores all unused control strings. Unused control strings include all Operating System commands (OSC), Privacy Messages (PM), and Application Program commands (APC), as well as all Device Control strings (DCS), unless they are within Sixel Graphics mode.
• After OSC receives an ESC, CAN SUB, ST or C1, it will: 1) enter Text mode 2) ignore any other characters • After PM receives an ESC, CAN SUB, ST or C1, it will: 1) enter Text mode 2) ignore any other characters • After APC receives an ESC, CAN SUB, ST or C1, it will: 1) enter Text mode 2) ignore any other characters 7–120 Digital Emulation
Drawing Vectors (DECVEC) ASCII Code ESC [ Pn1 ; Hex Code 1B 5B Pn1 3B Pn2 3B Pn3 3B Pn4 3B Pn5 3B 21 7C Dec Code 27 91 Pn1 59 Pn2 59 Pn3 59 Pn4 59 Pn5 59 33 124 Purpose Draw horizontal or vertical lines with length and width Discussion Margins do not affect line drawing so you can draw lines to the physical limits of the page. The DECVEC command sequence draws vectors without changing the currently active position.
Block Characters The block character sequences define the parameters of the block characters, initiate the generation of block characters, and return the printer to normal printing. The following subsections describe how to enact these features. Setting Block Character Parameters (DECBCS) ASCII Code ESC [ P1; P2;...P5‘r Hex Code 1B 5B P1 3B P2 3B...P5 27 72 Dec Code 27 91 P1 59 P2 59...P5 39 114 Purpose Defines the parameters for block characters.
Setting Block Character Parameters (DECBCS) (continued) The horizontal intercharacter gap for 0 degrees and for 180 degrees rotation is 1/60 in times the horizontal magnification factor. Characters rotated 90 degrees and 270 degrees have a horizontal intercharacter gap of 3/60 in times the vertical magnification factor. • P2 defines the vertical magnification factor. The maximum value of P2 is limited by page length.
Setting Block Character Parameters (DECBCS) (continued) • P5 specifies the block character’s orientation. P5 0/missing Function Same as current orientation 1 Portrait (0 degree rotation 2 3 Landscape (90 degree rotation) Reverse landscape (270 degree rotation) 4 Portrait upside down (180 degree rotation) NOTE: When the sequence selects character rotation, each character is rotated around its axis by the above specified degree.
Stop Block Character Mode ASCII Code ESC % @ Hex Code 1B 25 40 Dec Code 27 37 64 Purpose Stops the generation of block characters Discussion Once the block character sequence is stopped, the font attributes, the CPI settings, and the LPI settings are returned to their previous values. Printer Reset The sequences below reset the printer to predetermined operating features and conditions. These default operating conditions are listed in the next section.
Selecting IBM Proprinter Emulation via DECIPEM Digital emulation is the default when printer power is turned on, but you can select IBM Proprinter emulation with one control sequence, the Enter IBM Proprinter Emulation sequence (DECIPEM): ASCII: Hex: CSI 9BH ? 3FH 5 35H 8 38H h 68H This sequence performs the same function as the Select Other Coding System (SOCS) sequence.
Selecting IBM Proprinter Emulation via SOCS Digital emulation is the default when printer power is turned on, but you can select Proprinter emulation with one control sequence, the Select Other Coding System (SOCS) sequence: ASCII: Hex: ESC 1BH % 25H = 3DH SOCS resets IBM emulation mode to its initial conditions, which include: • Downloaded buffer • Character and line pitch • Character attributes • Print density • Form length • Tabs • Active Character Set The only valid Digital–compatible
7–Bit and 8–Bit Transmissions and Interpretations This section explains how to select 7–bit or 8–bit encoding of control strings. Select 7–Bit C1 Transmission (S7C1T) The sequence below causes the printer to use 7–bit encoding for all C1 control characters transmitted. All C1 characters are then represented as two–character ESC sequences.
Enter Draft Mode ASCII Code ESC % / 3 Hex Code 1B 25 2F 33 Dec Code 27 37 47 51 Purpose Puts the emulation into high speed draft print mode. Discussion All text following this command will be printed in the high speed draft font. This mode is slightly faster than the normal printing mode because of the simplified font. The high speed draft font can also be selected using the operator’s control panel. (Refer to Chapter 4.
Default Values and States The printer stores a set of typical operating states and conditions in ROM. The first time you power up the printer, the factory settings in Table 7–22 are automatically invoked. Table 7–22.
Upon receipt of a reset, the printer uses the default values in Table 7–23. Table 7–23.
At power–up, the parameter values in Table 7–24 are automatically retained from the previous power–on session. Table 7–24.

IBM Proprinter Emulation Emulation refers to the ability of a printer to execute the commands of other printer control languages. In IBM Proprinter Emulation mode, the printer prints files coded for the Proprinter. You can choose one of three ways to select Proprinter emulation, as explained in “Selecting IBM Proprinter Emulation” below. A printer control language (also called a printer protocol) is the coding system used to convey, manipulate, and print data.
6. Press ENTER. An asterisk ( * ) appears after the display message; that is, “Emulation Proprinter XL * ” displays. This means that the printer has set all configuration values associated with the emulation. The values are those previously saved when the Proprinter emulation was selected. If no values were altered, the factory default values for Proprinter emulation are loaded. 7. Press CLEAR to return to “Off–line Emulation.” 8. Press UP and DOWN simultaneously to lock the ENTER switch.
To exit IBM Proprinter emulation, enter the following escape sequence: ASCII: Hex: ESC 1BH [ 5BH ? 3FH 5 35H 8 38H 1 6CH Note that the CSI sequence (the Enter DECIPEM sequence) cannot be used in place of the Exit IBM Proprinter Emulation mode. In IBM mode, the CSI is processed as an ESC.
ASCII: Hex: ESC c 1B 63 or by sending a Soft Terminal Reset (DECSTR) control sequence: ASCII: Hex: ESC [ ! p 1B 5B 21 70 These sequences accomplish the same reset function. Do not use the CSI command sequence for the DECSTR control string. Graphics Proprinter emulation provides one data protocol for printing graphics information. Bit Image graphics protocol allows an image block to be printed. When using Bit Image protocol, you can mix text and graphics on the same line.
Dot Density Versus Printing Speed When you select ESC K (normal density), the dot columns are printed at 60 dpi horizontally and 75 dpi vertically. This does not decrease the speed of the print engine. If ESC L (double density) is selected, the dot columns are printed at 120 dpi horizontally and 75 dpi vertically. Double density reduces the speed of the print engine by one half.
Character Sets The printer emulates IBM’s Code Page 437 and Code Page 850, which are shown in Appendix C. Code Pages A code page is a set of symbols printed by the Proprinter emulation. These symbols consist of letters, numbers, or graphic elements. The Proprinter emulation supports different language requirements by utilizing different code pages. The Proprinter emulation uses characters from code pages 437 and 850. These pages are set up in a table format, as described in the following subsection.
Example A sample written in BASIC programming language is provided when it is possible to illustrate the effect of a control code or if a specific syntax is required. The programs in this chapter were run on an IBM Personal Computer using Microsoft GW–BASIC version 3.22. Ignored Codes Table 8–1 lists control codes that are ignored by the Proprinter emulation. Table 8–1.
Table 8–1. Ignored Codes (continued) ESC 60 – FF ––– 1 Note 1: Can occur at any place in the datastream and is acted upon immediately. Note 2: If this code is also used in the Serial Interface Protocol (SIP), the SIP function takes precedence over the control code definition. Table 8–2 lists control codes not implemented at this time. The codes are usually followed by large blocks of data. The Proprinter emulation ignores the control code and any data applicable to that control code. Table 8–2.
Control Code Index and Descriptions This index lists each printer command by function, ASCII mnemonic, and the page where the command is explained in detail. N/A means not applicable.

Backspace ASCII Code BS Hex Code 08 Dec Code 08 Purpose Moves the logical print head left one character space toward the first character column. Discussion This code locks the current data in the string buffer, which allows certain control codes to emulate immediate printing of the buffer. CAN clears data in the buffer that should be printed. This code is ignored if the logical print head is positioned at the first character column.
Bit Image Mode, Normal Density ASCII Code ESC K n1 n2 Hex Code 1B 4B Dec Code 27 75 n1 n2 Expression CHR$(27);”K”;CHR$(n1);CHR$(n2);”DATA” Purpose Selects Single (Normal) Density Bit Image graphics. where Discussion n1 + 256 n2 define the number of data bytes to follow. DATA = ASCII characters for the dot pattern bytes. For more information, see “Graphics,” page 8–5. This code can occur at any place in the datastream and is acted upon immediately.
Bit Image Mode, Double Density ASCII Code ESC L n1 n2 Hex Code 1B 4C Dec Code 27 76 n1 n2 Expression CHR$(27);”L”;CHR$(n1);CHR$(n2);”DATA” Purpose Selects Double Density Bit Image graphics. where Discussion n1 + 256 n2 define the number of data bytes to follow. DATA = ASCII characters for the dot pattern bytes. All data following this code are printed in bit image graphics at double the current horizontal dot density. The current vertical dot density is unchanged.
Bit Image Mode, Double Density, Double Speed ASCII Code ESC Y n1 n2 Hex Code 1B 59 Dec Code 27 89 n1 n2 Expression CHR$(27);”Y”;CHR$(n1);CHR$(n2);”DATA” Purpose Prints double density graphics at twice the speed of double density by ignoring adjacent dots. where n1 + 256 n2 define the number of data bytes to follow. DATA = ASCII characters for the dot pattern bytes. Discussion This code can occur at any place in the datastream and is acted upon immediately.
Bit Image Mode, Quadruple Density ASCII Code ESC Z n1 n2 Hex Code 1B 5A n1 n2 Dec Code 27 90 n1 n2 Expression CHR$(27);”Z”;CHR$(n1);CHR$(n2);”DATA” Purpose Selects Quadruple Density Bit Image graphics. where n1 + 256 n2 define the number of data bytes to follow. DATA = ASCII characters for the dot pattern bytes. Discussion This code can occur at any place in the datastream and is acted upon immediately. Print speed is reduced by half. For detailed information, see “Graphics,” page 8–5.
Bottom Margin Set ASCII Code ESC N n Hex Code 1B 4E n Dec Code 27 78 n Purpose Sets the bottom margin. Discussion n defines the number of lines above the bottom of the form to set as the bottom margin. n has a range from 1 through 255. If a line feed command causes the active position to advance below the bottom margin, the paper advances to the top of the next form. If the page length is equal to or greater than the form length, the length is reset to the length of the form.
Cancel ASCII Code CAN Hex Code 18 Dec Code 24 Purpose Clears the print buffer of all printable symbols since the last paper motion command was received. Discussion The CAN command cancels all printable characters sent to the printer from the last paper motion command. If any attribute command is sent before a CAN command, all data before the attribute command are printed unless the attribute command is a Horizontal Tab command. This command will cancel the double wide attribute if set by SO.
Character Pitch 12 cpi ASCII Code ESC : Hex Code 1B 3A Dec Code 27 58 Purpose Sets character pitch to 12 cpi. Discussion Character pitch can also be set via front panel controls. Refer to Chapter 4, “Configuration,” for instructions. An ESC : code overrides any front panel setting. An ESC : code can occur at any place in the datastream and is acted upon immediately. Clear Tabs ASCII Code ESC R Hex Code 1B 52 Dec Code 27 82 Purpose Clears all horizontal and vertical tab stops.
Condensed Print Select ASCII Code SI ESC SI Hex Code 0F 1B 0F Dec Code 15 27 15 Purpose Selects up to 20 characters per inch (cpi) condensed print format. Discussion The condensed print command SI affects all subsequent characters. After receiving code SI, all characters are printed in condensed print until reset by the Condensed Print Cancel command, DC2, printer reset, or a new print mode command. The Proprinter SI code (hex 0F) is equivalent to the ESC SI code.
Condensed Print Cancel and Set to 10 CPI ASCII Code DC2 ESC DC2 Hex Code 12 1B 12 Dec Code 18 27 18 Purpose Cancels condensed character printing and sets pitch to 10 cpi. Discussion The Cancel Condensed Print command resets 6, 8.55, 12, 17.1, or 20 cpi pitch to 10 cpi character pitch. Other print attributes are not affected. Cancel Condensed Print command can occur at any place in the datastream and is acted upon immediately.
Double Strike Printing (Select) ASCII Code ESC G Hex Code 1B 47 Dec Code 27 71 Purpose Selects double strike (bold) character printing. Discussion When this command is received, all characters are printed in double strike until reset by the Double Strike Print reset command or printer reset. Double strike printing is ignored for scripts and double high printing. Double strike printing can occur at any place in the datastream, is acted upon immediately, and reduces the print speed.
Double Strike Printing (Cancel) ASCII Code ESC H Hex Code 1B 48 Dec Code 27 72 Purpose Cancel double strike character printing. Discussion The Double Strike Print Cancel command only cancels the double strike print character attribute. Other print attributes such as double wide printing are not affected. An ESC H code can occur at any place in the datastream and is acted upon immediately.
Double Wide Print ASCII Code ESC W n Hex Code 1B 57 n Dec Code 27 87 n Purpose Selects or cancels double wide print. Discussion An ESC W code sets or cancels double wide print as follows: The value of n is in the 00 to FF hex range. If n = odd, double wide print is selected for all following lines. If n = even, double wide print is cancelled for all following lines. When expanded print using ESC W is received, all characters print double wide until cancelled by an even parameter hex code.
Double Wide Print (One Line Only) ASCII Code SO Hex Code 0E Dec Code 14 Purpose Selects double wide print for one line only. Discussion This expanded print command is a line–by–line print attribute; when the SO or ESC SO command is received, the current line will be printed double wide and automatically reset. This command can be reset by a paper motion command (LF, VT, CR), by the DC4 (double wide cancel) code, CAN or ESC W (double wide print).
Double Wide Print (Cancel) ASCII Code DC4 ESC DC4 Hex Code 14 1B 14 Dec Code 20 27 20 Purpose Cancels double wide print, if it was set by command SO. Discussion The DC4 code cancels Double Wide Print command SO. If Double Wide Print is not enabled, the DC4 code is ignored. A DC4 code can occur at any place in the datastream and is acted upon immediately.
Emphasized Print (Select) ASCII Code ESC E Hex Code 1B 45 Dec Code 27 69 Purpose Selects emphasized character print format. Discussion When the emphasized print command is received, all characters will be printed in emphasized print until reset by the Emphasized Print Reset command or printer reset. The emphasized print attribute can be used in either NLQ or Draft mode. An ESC E code can occur at any place in the datastream and is acted upon immediately.
Emphasized Print (Cancel) ASCII Code ESC F Hex Code 1B 46 Dec Code 27 70 Purpose Cancels emphasized character printing. Discussion The emphasized print reset command only resets the emphasized print character attribute. An ESC F code can occur at any place in the datastream and is acted upon immediately.
Escape Printer capability is greatly increased by combining character codes into escape sequences. Escape sequences always begin with the ASCII escape sequence introducer, ESC (hex 1B). An ESC sequence introducer in the data stream signals the printer to wait for special instructions. The character codes following the ESC character tell the printer what to do. NOTE: For readability, code sequences appear in this manual with spaces inserted between command elements.
Form Feed ASCII Code FF Hex Code 0C Dec Code 12 Purpose Prints the data in the buffer, advances the paper to the next top–of–form, and moves the printhead to the first character column. Discussion The default forms length is determined by the configuration in nonvolatile memory. Forms length is set by using the control panel form length setting or forms length commands. Code FF cancels double wide (expanded) characters if set by the SO command.
Forms Length Set (Inches) ASCII Code ESC C 0 n Hex Code 1B 43 00H n Dec Code 27 67 0 n Purpose Sets the length of forms (paper) in inches. Discussion When ESC C 0 n sets the forms length, n alone is measured in inches, with a range of 1 through 21. All other values are ignored. If the active print position is set to column 1, line 1 and printing has occurred on the page, perform a form feed to clear the buffer. If no printing has occurred, you need not invoke a form feed command.
Forms Length Set (Lines) ASCII Code ESC C n Hex Code 1B 43 n Dec Code 27 67 n Purpose Sets the length of a form (paper) in lines. Discussion When forms length is set by the ESC C n sequence, it is the product of the parameter n and the current line spacing. The range of n is 1 through the total number of lines that total 21 inches at the current line spacing. When necessary, the form length is rounded to the nearest dot row position.
Horizontal Tab ASCII Code HT Hex Code 09 Dec Code 09 Purpose Moves the logical printhead right to the next horizontal tab stop. Discussion Power–on default horizontal tabs are set at every eighth character in the Proprinter protocol. If there are no horizontal tabs set or the logical printhead is located at the last character column, the code is ignored and no movement occurs. If double wide, double high attributes are enabled, single wide character spacing is used.
Horizontal Tab Set ASCII Code ESC D n1 n2 nk 0 Hex Code 1B 44 n1 n2 nk 30 Dec Code 27 68 n1 n2 nk 48 Purpose Sets up to 28 horizontal tab positions. Discussion n denotes the character column position, at the current character pitch, for each tab stop in relation to character column one. n can range from 1 through 255, inclusive, and all parameters must be in ascending order. Any out–of–order symbols are ignored, though the remainder of the sequence is processed.

Discussion Values n1, n3, and n4 define the bits that set various conditions for the printer. Setting parameter n1 performs two functions: 1) Values 00–01 load and change the bits for parameters n3 and n4 to pre–configured settings. 2) Values FE and FF save the custom settings for parameters n3 and n4.

Line Feed ASCII Code LF Hex Code 0A Dec Code 10 Purpose Prints the data in the buffer (if any) and advances the paper one line at the current line space setting. Discussion If configured for LF equals new line (LF = CR + LF), the logical print head is positioned at character column 1 of the new line. Otherwise, the logical print head does not move when configured for LF function only (LF = LF ONLY). The LF function cancels double wide (expanded) characters if set by the SO command.
Line Feed n/216 Inch ASCII Code ESC J n Hex Code 1B 4A n Dec Code 27 74 n Purpose Advances paper n/216 inches for one line only. Discussion The range of n is 1 through 255. The value of n must be an integer multiple of 3 to move paper exactly n/216 inches. Example The following example illustrates n/216–inch line spacing.
Line Spacing 1/8 Inch (8 lpi) ASCII Code ESC 0 Hex Code 1B 30 Dec Code 27 48 Purpose Specifies continuous line spacing at 1/8–inch increments (8 lpi). Discussion When the 1/8–inch line spacing command is received, all lines will be printed at 8 lpi until a new line spacing is selected or power is recycled. All control codes that define vertical distance expressed in inches are stored internally in units of paper drive steps.
Line Spacing 7/72 Inch (10.3 lpi) ASCII Code ESC 1 Hex Code 1B 31 Dec Code 27 49 Purpose Specifies the line spacing at 7/72–inch (10.3 lpi) increments. Discussion When the 7/72–inch line spacing command is received, all lines will be printed at the 7/72–inch line spacing until a new line spacing is selected or power is recycled. The line spacing will be set at 10.3 lines per inch.
Line Spacing n/72 Inch (Executes) ASCII Code ESC 2 Hex Code 1B 32 Dec Code 27 50 Purpose Executes line spacing as set by ESC A. Discussion All NL or LF commands move the paper n/72–inch line spacing until a new line spacing is selected or power is recycled. If a distance has not been selected by ESC A, the default setting, 1/6–inch, is used. All control codes that define vertical distance expressed in inches are stored internally in units of paper drive steps.
Line Spacing n/72 Inch (Storage) ASCII Code ESC A n Hex Code 1B 41 n Dec Code 27 65 n Purpose Stores a line spacing of n/72–inch increments. Discussion Line spacing can be set in any increment from 1 to 255, inclusive. All other n values cause the command sequence to be ignored up to the point of the detected error. Subsequent symbols are then interpreted. To execute this setting, refer to “Line Spacing n/72 Inch (Execution),” page 8–42.
Line Spacing n/216 Inch ASCII Code ESC 3 n Hex Code 1B 33 n Dec Code 27 51 n Purpose Sets graphic line spacing of n/216 for bit–image graphics using 8 bits. Discussion The range of n = 1 – 255. The value of n must be an integer multiple of 3 to move exactly n/216 inch. Example The following example illustrates n/216–inch line spacing.
Near Letter Quality Print ASCII Code ESC I Hex Code 1B 49 n Dec Code 27 73 n Purpose Selects a font. Discussion Select a font using the following choices: n Hex Function X0 Draft X1 Draft X2 NLQ X3 NLQ X4 Draft X5 Draft X6 NLQ X7 NLQ XB NLQ underlined XF NLQ The current pitch is not affected.
Overscoring ASCII Code ESC _ n Hex Code 1B 5F n Dec Code 27 95 n Purpose Enables or disables automatic overscoring of all characters. Discussion When automatic overscore is enabled, all characters (including spaces and spaces resulting from tabs) are overscored until disabled. Full–height graphic characters are not printed with overscores.

Epson Emulation Emulation refers to the ability of a printer to execute the commands of other printer control languages. In Epson emulation mode, the printer prints files coded for Epson FX series printers and emulates certain features of Epson 850/1050 printers. You can configure the printer from the control panel to respond to Epson FX series control codes. (See “Selecting Epson FX Emulation” on page 9–3.
Selecting Epson Emulation You select the Epson emulation from the control panel: 1. If the printer is on–line, press the ON LINE switch to place it in the off–line state. “Off–Line Emulation” appears on the message display. 2. Open the printer cover. 3. On the control panel, press UP and DOWN simultaneously to unlock the ENTER switch. “Unlocked” appears briefly on the message display. (If “Locked” appears, simply press UP and DOWN again.) 4. Press DOWN to enter the emulation menu.
Default Values and States, Epson Emulation The printer stores a set of typical operating states and conditions in ROM. The first time you power up the printer, the factory settings in Table 9–1 are automatically invoked. Table 9–1. Factory Settings, Epson Emulation Characteristic Default Setting Font Draft 10 Condensed No Character Set Epson International Set USA Slashed Zero No CR = CR Default Page Length 11 inches Default Skip Over Perf No Default Page Width 9–4 13.
Epson Character Sets Epson printers use two character sets. One is the IBM Graphics Code Page 437. The other set is unique to Epson. The Epson character set is basically the ASCII character set with the upper, non–ASCII set defined as italics, and the usually unprintable codes reassigned as international characters. In the LG06 and LG12 printer, the Epson italic character set prints underlined. (See Figure 9–1.) Figure 9–1.
Escape Sequences An Epson control code consisting of more than one character is called an escape sequence because the first charcter in the sequence is always the ASCII ESCape character. ESC alerts the printer that a special function command—not printable characters—follows. The general format for an escape sequence is: (ESC)(parameter 1)(parameter 2)...
How Control Codes are Described in this Chapter The following information is listed for each code (where applicable and possible): ASCII Mnemonic – The ASCII name for the control code. Hex Code – The hexadecimal equivalent of the code. (For decimal and octal equivalents, refer to Appendix A.) Purpose – The function(s) of the control code. Comment – A description of exceptions or limitations to normal use.
Control Code Index and Descriptions The following index lists the control codes by function, ASCII mnemonic, and page number. Some control code functions can also be selected at the control panel. † = Produces non–Epson behavior in the printer.
† = Produces non–Epson behavior in the printer. † † † Set Intercharacter Spacing in 1/120”.
† = Produces non–Epson behavior in the printer.
Line Feed ASCII Code LF HEX Code 0A Purpose Prints the data in the buffer (if any) and advances the vertical character postion a distance of one line at the current line spacing. Comment The simulated print head keeps the same distance from the margin. The current line is printed and the simulated printhead moves down a distance equal to the current line spacing. If there are no dots, paper moves and no printing occurs. When possible, successive line feeds are accumulated and moved at once.
Line Feed n/216 Inch ASCII Code ESC J n HEX Code 1B 4A n Purpose Immediately advances the paper n/216 inch. where Comment n = 0 to 255 inclusive n = 0 is ignored. Paper movement occurs in multiples of 3/216 inch. This command produces an immediate line feed but does not affect line spacing or produce a carriage return. Any one–line–only print attributes in effect are canceled. Small values of n may result in overlapping lines.
Backward Line Feed n/216 Inch (One Line) ASCII Code ESC j n HEX Code 1B 6A n Purpose Immediately moves the paper backward n/216 inch. where † Comment n = 0 to 255 inclusive This command is ignored by the printer. Form Feed ASCII Code FF HEX Code 0C Purpose Prints the data in the buffer, if any, then moves the paper to the top of the next form Comment The simulated print head moves to the left margin.
Set Page Length by Lines ASCII Code ESC C n HEX Code 1B 43 n Purpose Sets the page length by lines. where Comment n = hex 1 to hex 7F, to specify the number of lines per page at the current line spacing. The current line becomes the first line of the form. The forms length units are always defined in inches; therefore, subsequent line spacing changes do not affect the result of this command. Changing lpi does not change the forms length.
Set Page Length in Inches ASCII Code ESC C 0 n HEX Code 1B 43 30 n Purpose Sets page length to n inches. where Comment n = whole numbers (hex values) from 1 to 24 to specify the number of inches on a page. Upon receipt of this code, the current line becomes the first line of the form, and the form length set becomes the current forms length. Vertical tab positions set below the bottom of the form are ignored.
Skip Over Perforation ASCII Code ESC N n HEX Code 1B 4E n Purpose Selects the number of lines (at the current line spacing) for the paper to skip at the bottom of the perforated page. where Comment n = 1 to 127. n is the number of lines skipped between the last line printed on one page and the first line on the next page. The actual distance set is the product of n and the current line spacing.
Vertical Tab, Execute ASCII Code VT HEX Code 0B Purpose Advances the simulated print head to the next vertical tab position selected by ESC /. Comment If no vertical channel was selected, channel 0 is used. If no vertical tabs were set, the paper advances one line. The simulated print head moves to left margin. If a tab position is on the current line, the paper is moved to the next tab position.
Vertical Tab, Set/Clear ASCII Code ESC B n1 n2 n3...nk NUL HEX Code 1B 42 n1 n2 n3...nk 00 Purpose Sets up to 16 vertical tab positions. where n = 0 to 255 and k = 1 to 16 n1 through nk specify the line number for the vertical tab(s), up to a maximum of 16 tab positions. NUL must end the sequence. To clear the tab settings, send ESC B NUL (1B 42 00). Expression CHR$(27);”B”;CHR$(n1);...CHR$(nk);CHR$(0); Comment The values of n range from 1 to 255 and must be in ascending order.
Select Vertical Tab Channel ASCII Code ESC / c HEX Code 1B 2F c Purpose Selects a vertical tab channel set by ESC b. where Comment Epson FX Emulation c = 0 through 7. Subsequent VT (Hex 0B) commands use tab table specified by c. If no tab table is selected, table 0 is used.
Set Vertical Tabs in Channels ASCII Code ESC b c n1 n2 n3 ... nk 0 HEX Code 1B 62 c n1 n2 n3 ... nk 00 Purpose Assigns vertical tabs to channels established by ESC /. where Comment c = 0 through 7 nx = 0 through 255 Channels are selected by ESC /. The most significant bit of all the n values is cleared when read, so that hex 81 becomes hex 1, and hex 80 becomes hex 0 which ends the load. The distance of each tab stop from TOF is the current line spacing times the number of lines given in n.
Line Spacing 1/6 Inch (6lpi) ASCII Code ESC 2 HEX Code 1B 32 Purpose Sets the line spacing to 1/6 inch for subsequent line feeds. Comment The 2 is ASCII character 2, not hex 2. This control code overrides line spacing set at the control panel. Example Epson FX Emulation The following example illustrates 1/6–inch line spacing.
Line Spacing 1/8 Inch (8 lpi) 9–22 ASCII Code ESC 0 HEX Code 1B 30 Purpose Sets the line spacing to 1/8 inch (8 lpi) for subsequent line feeds. Comment When ESC 0 is received, all lines are printed at 8 lpi until a new line spacing is selected or power is reset. This control code overrides line spacing set at the control panel. Example The following example illustrates 1/8–inch line spacing.
Line Spacing 7/72 Inch ASCII Code ESC 1 HEX Code 1B 31 Purpose Sets the line spacing to 7/72 inch (10.3 lpi) for subsequent line feeds. Comment All lines are printed at the 7/72–inch line spacing until a new line spacing is selected or power is reset. This control code overrides line spacing set at the control panel. Printing speed is reduced if printed lines overlap. Example Epson FX Emulation The following example illustrates 7/72–inch line spacing.
Line Spacing n/216 Inch ASCII Code ESC 3 n HEX Code 1B 33 n Purpose Specifies the line spacing at n/216–inch increments. where Comment n = 1 to 255 All line feeds following receipt of this code are at n/216 inch line spacing until a new line spacing is selected or power is reset. Line spacing set by this control code overrides line spacing setting set at the control panel.
Line Spacing n/72 Inch ASCII Code ESC A n HEX Code 1B 41 n Purpose Sets a line spacing of n/72 inch for subsequent line feeds. where Comment n = 0 to 85 (all other values are ignored) When this control sequence is received, all subsequent line feeds are n/72–inch until a new line spacing is selected or power is reset. This setting overrides line spacing set at the control panel. Small values of n may result in overlapping lines.
Disable Paper Out Detection ASCII Code ESC 8 HEX Code 1B 38 Purpose Enable printing to the end of the paper supply when a paper out condition is sensed. † Comment The printer decodes and ignores this command. This command is defined for the Epson FX–850 and FX, but not for the DFX–8000. Enable Paper Out Detection 9–26 ASCII Code ESC 9 HEX Code 1B 39 Purpose Asserts a paper out condition immediately when the end of the paper supply is sensed.
Backspace ASCII Code BS HEX Code 08 Purpose Moves the simulated print head to the left one character space toward the first character column. Comment Assures that the previous printable characters will be printed, then moves the simulated print head one character space to the left at the current pitch setting (which includes double wide and ESC SP). If the simulated print head bumps into the left margin, it stops.
Horizontal Tab Execute ASCII Code HT HEX Code 09 Purpose Moves the simulated print head to the next horizontal tab stop. Comment Power–on default horizontal tabs are set at every eighth character at the current character spacing. Tab positions are not affected by a change of font or character width. Blank spaces between HT stops are not underlined in underline mode. This command is ignored if a justification mode ESC a n is set with n 0, emulating the FX.
Horizontal Tab Set/Release ASCII Code ESC D n1 ... nk HEX Code 1B 44 n1 ... nk Purpose Sets up to 32 horizontal tab positions. Expression CHR$(27);”D”;CHR$(n1);...CHR$(n32);CHR$(0); where Comment n1 through n32 specify the character column of the tab positions. CHR$(0) is the sequence terminator. n = 0 clears all tabs. The values of n must be listed in ascending order or they are ignored. Tabs greater than 32 or those positioned beyond the right margin are ignored.
Set Absolute Horizontal Print Position in 1/60 Inch ASCII Code ESC $ n1 n2 HEX Code 1B 24 n1 n2 Purpose Moves the simulated print head to an absolute horizontal print position, using 1/60 inch increments. where (n1 + (n2 x 256)) = the unsigned distance in inches from the left 60 margin. Comment If the distance goes beyond right margin, the sequence is ignored.
Character Pitch 12 CPI ASCII Code ESC M HEX Code 1B 4D Purpose Sets character pitch to 12 characters per inch (cpi). Comment This command is available in both DP and NLQ print modes. Character Pitch 10 CPI ASCII Code ESC P HEX Code 1B 50 Purpose Sets character pitch to 10 characters per inch (cpi). Comment This command is available in both DP and NLQ print modes. This command is normally used to cancel 12 cpi.
Set Right Margin ASCII Code ESC Q n HEX Code 1B 51 n where n = number of columns from the right edge of the physical page to the end of the print line. Purpose Sets the right margin to n columns at the current character width. Comment The number of inches of margin does not vary if the font, character width, or horizontal dot density changes. This command automatically clears and resets horizontal tabs to every eight characters, then performs a CAN operation.
Select Proportional Spacing ASCII Code ESC p n HEX Code 1B 70 n Where n is an integer Purpose Turns proportional mode on and off. † Comment This command is ignored by the printer.
Double Wide Print (One Line) ASCII Code SO ESC SO HEX Code 0E 1B 0E Purpose Selects double wide print for one line only. Comment This control code is a line–by–line print attribute; when SO or ESC SO is received, the current line prints twice as wide then automatically resets. This control code is cancelled by the DC4 code, by a paper motion control code (LF, VT, etc.), or by CR. Example 9–34 The following program illustrates double wide print for one line only.
Double Wide Print ASCII Code ESC W n HEX Code 1B 57 n Purpose Turns double wide print on and off. where n = hex 1 or hex 31 turns double wide print on n = hex 0 or hex 30 turns double wide print off Comment When ESC W is received, all characters are printed twice as wide until reset. This command overrides SO, ESC SO, and DC4. Example The following program illustrates double wide character printing.
Double High Print, Set/Reset ASCII Code ESC w n HEX Code 1B 77 n Purpose Turns double high character printing on and off. Double high characters are standard width but twice as high. where † Comment n = hex 1 or hex 31 turns double high printing on n = hex 0 or hex 30 turns double high printing off Superscript, subscript, and condensed modes are not available in double high mode, but resume when this mode is turned off.
Condensed Print ASCII Code SI ESC SI HEX Code 0F 1B 0F Purpose Condenses print pitch as close to 60% of the former character width as possible. Comment Draft 10 cpi condenses to Draft 17 cpi. Draft 12 and 15 cpi condense to Draft 20. NLQ 10, 12, or 15 cpi condense to NLQ 16.4 cpi. Control code SI affects all subsequent characters. After receiving code SI, all characters are printed condensed until the printer is reset by ESC M, ESC P, DC2, a printer reset, or a new print mode control code.
Condensed Print Reset ASCII Code DC2 HEX Code 12 Purpose Cancels the condensed print mode set by SI, ESC SI, or the control panel. Comment This returns the printer to font that was active before condensed print occurred. Other print attributes are not affected. Example See the Condensed Print control code (page 9–37) for an example of Condensed Print Reset. Underline ASCII Code ESC – n HEX Code 1B 2D n Purpose Turns automatic underlining on and off.
Select Italic Printing ASCII Code ESC 4 HEX Code 1B 34 Purpose Turns on italic character printing. † Comment The printer substitutes underlining for italic character printing. White spaces skipped by HT are not underlined. Character graphics (IBM graphic set hex B0 to DF and F0 to FE) cannot be italicized. Cancel Italic Printing ASCII Code ESC 5 HEX Code 1B 35 Purpose Turns off italic character printing.
Emphasized Print ASCII Code ESC E HEX Code 1B 45 Purpose Selects emphasized character print format. Comment Emphasized print makes text bolder by printing each dot twice, the second dot offset to the right of the first by a distance equal to 1/2 the width of a dot. This command is available in both draft and NLQ modes. Example The following program illustrates emphasized character printing.
Select Double Strike ASCII Code ESC G HEX Code 1B 47 Purpose Makes text bolder by double printing each dot twice. † Comment This command makes text bolder by printing each dot twice, the second dot offset to the right of the first by a distance equal to 1/2 the width of a dot, the same as with ESC E. Double strike is disabled in NLQ mode (emulating all Epson printers). Example The following program illustrates double strike character printing.
Superscript and Subscript Printing ASCII Code ESC S n HEX Code 1B 53 n Purpose Selects superscript or subscript printing. where Comment n = NUL (hex 00) or 0 (hex 30) to enable superscript printing n = SOH (hex 01) or 1 (hex 31) to enable subscript printing Superscript prints full–sized characters 3/72 inch higher than the normal characters. Subscript prints full–sized characters 3/72 inch lower than the normal characters.
Cancel Superscript and Subscript Printing ASCII Code ESC T HEX Code 1B 54 Purpose Cancels superscript and/or subscript printing as set by ESC S n. Master Font and Emphasis Select ASCII Code ESC ! n HEX Code 1B 21 n Purpose Selects or changes print attributes in a single command. where n = an 8–bit number with the bits set to specify fonts and attributes, as shown in Table 9–2 below. Table 9–2. Epson Master Select Options † Comment Epson FX Emulation Bit No.
Select User–Defined Font ASCII Code ESC % n HEX Code 1B 25 n Purpose Selects a user–defined font. † Comment The printer ignores this command and removes all sent font data from the data stream. Define a Download Character ASCII Code ESC & HEX Code 1B 26 Purpose Defines a download character. † Comment The printer ignores this command and removes all sent font data from the data stream.
Character Pitch 15 CPI ASCII Code ESC g HEX Code 1B 70 Purpose Sets character pitch to 15 characters per inch (cpi). † Comment This command is not defined in Epson printers. It is included in this emulation for compatibility with the Okidata KX–P1180 printer. Select Serif or Sans Serif Font ASCII Code ESC k n HEX Code 1B 78 n Purpose To select an NLQ font.

Printing Graphic Images The printer can produce bit image graphics when it is in Proprinter emulation mode. In either emulation, however, text printing is the default mode. Consequently, every line of graphics data must include the necessary plot mode command to enable the printer to perform graphics functions. You can combine text and graphics on the same line when using the bit image protocol in the Proprinter Emulation mode.
Making a Bit Image Pattern A Bit Image pattern is produced in four steps: 1. On a quadrille pad or graph paper, lay out the graphic pattern you want to print and divide the pattern into vertical data bytes. 2. Determine the decimal equivalent of each bit image data byte required to produce your pattern. (See Figure 10–1.) 3. Write a program to generate the complete pattern. 4. Enter and run the program on the host computer.

Bit Image Pattern from an ASCII Character Bit Image Density You can print bit image graphics in different dot densities. Select dot densities by sending a control code in the datastream: • ESC K selects the Single Density mode. Single Density bit image graphics are printed at 60 dots per inch (dpi) horizontally and 75 dpi vertically.
When printing Quadruple Density graphics, the printer pairs adjacent quadruple density bit image bytes. The compounded data are then printed in the Double Density mode. Printing at quadruple density reduces the printing speed by half.

Introduction The Digital, Proprinter, and Epson emulations offer different character sets and language overlays. The character sets shown in this chapter are accessable only in Digital emulation mode. Digital and Proprinter character set matrices and language substitution tables are provided in Appendix C. Epson FX printers can access two character sets: the Epson character set illustrated in Chapter 9 and the Proprinter Code (Page 437) shown in Appendix C.
Numeric Character Location Listing Graphic symbols of the ASCII character set are listed in numeric order by hexadecimal address. Included is the decimal code and the symbol’s name. Table 11–1.

User Preference Supplemental (UPS) Character Sets A symbol set is the alphabet of a font; it is a character set that can be printed regardless of the font characteristics designated for the print job. The default symbol set for the fonts in the printer is the U.S. ASCII set. The U.S. ASCII set is the base onto which other symbol set overlay sequences may be loaded. The default UPS character set is comprised of the DEC Supplemental character set and the ISO Latin 1 Supplemental character set.

DEC Supplemental Graphic Character Set The DEC Supplemental character set consists of graphic alphabetical symbols not included in the ASCII character set. Character positions identified as “reserved for future use” print the error character (reverse question mark). The following table gives the 7–bit code for each character. The equivalent 8–bit code is obtained by adding octal 200 or hex 80 to the 7–bit code. Table 11–21.

DEC Technical Character Set The DEC Technical Character Set contains Greek letters, mathematical symbols, and logical symbols. Additionally, it contains characters that may be used to construct larger mathematical symbols on character cell devices, such as large integral and summation signs. Select this character set via the control sequence, DECAUPSS, as described in Chapter 7.
Table 11–23.
Table 11–23.
Building Large Mathematical Symbols Table 11–24 shows how to build large mathematical symbols. The characters are designed to connect to adjacent character cells at 10 cpi and 6 lpi to form technical characters that can occupy several vertically adjacent and/or horizontally adjacent character positions. To use Table 11–24, find the character you want to build (along the top of the table). On the left side of the table are various pieces of the characters needed to create the whole.

Bar Codes A bar code is a graphic representation of alphanumeric characters that can be read by a scanning device. In Digital emulation, three escape sequences enable the printer to print bar codes. One escape sequence sets the bar code parameters, another starts bar code production, and the third sequence stops bar code printing. Select Bar Codes Attributes Sequence (DECSBCA) ASCII Code: ESC [ P1; P2;...P9‘q Hex Code: 1B 5B P1 3B P2 3B...P9 27 71 Dec Code: 27 91 P1 59 P2 59...
Default value = 10 pixels = 12 decipoints Minimum value = 9 pixels = 11 decipoints This does not apply to all UPC, EAN, and Postnet bar codes. • P3 sets the width for the quiet zone. The printer’s quiet zone is a constant pixel value of 150 pixels (180 decipoints) or ten times the narrow bar, whichever is greater. This does not apply to all UPC, EAN, and Postnet bar codes. • P4 sets the width of the wide bars and wide spaces in units specified by the SSU code. Default value = 2.
• P8 sets the orientation for the bar codes. Bar codes can be rotated to four different positions, though any characters beneath them are printed only in portrait or landscape orientations. The default is P8 = 0. P8 0/missing 1 2 3 4 • Function Same as current page orientation Horizontal (portrait) Vertical, rotation of –90o (landscape) Horizontal, upside down, rotation of 180o Vertical, rotation of +90o (landscape) P9 sets the human–readable character option.
Start Bar Coding (DECBARC) ASCII Code: ESC % SP 0 Hex Code: 1B 25 20 30 Dec Code: 27 37 32 48 Purpose: Generates bar codes using data that follow the sequence. Discussion: Bar code parameters are defined by the last DECSBCA sequence. The printer continues to encode bar codes until it receives the Stop Bar Code sequence. The printer begins to generate a bar code at the upper left–hand corner of the left quiet zone and ends at the lower right–hand corner of the right quiet zone.
Bar Code Characteristics The printer supports fifteen bar code styles: • Code 39 (default or user–selectable settings) • Extended Code 39 • Interleaved 2 of 5 • EAN 8 • EAN 13 • Code 11 • Codebar a/t • Codebar b/n • Codebar c/* • Codebar d/e • UPC–A • UPC–E • Postnet • Code 128 – USS (regular) • Code 128 – UCC (serial shipping container code) All bar code styles differ, though the differences can be subtle or obvious.
Bar Code Character Set Different bar code styles allow certain parts of the ASCII character set to be used. Some styles allow only the numerals 0 – 9, while others allow the full ASCII character set, and still others allow variations in between. START, STOP, and CENTER Code Characters The START/STOP characters identify the beginning and end of the bar code symbol to the bar code reader. The START code is at the left end of the symbol, next to the most significant character.
Checksums Checksums can be included within the bar code symbol. If a checksum digit is required for a particular style, it is computed by the user and sent along with the rest of the characters that make up the bar code symbol. The printer automatically computes the check digit and embeds it at the end of the bar code for the UPC, EAN, Code 11, Code 128, and Postnet bar codes. Parity You can use odd or even parity to send an individual character in styles EAN–8, EAN–13, UPC–A, and UPC–E.
Bar Code Styles The following sections discuss the bar codes the printer can make. The characteristics of bar code styles, P1 – P9 values, and their defaults are also discussed. Code 39 In the Code 39 style, there are five dark bars and four light bars for a total of nine bars. Three bars are wide and the other six are narrow. Both light and dark bars are coded to define the character. A narrow light/dark bar is assigned a binary 0 and a wide light/dark bar is assigned a binary 1.

Code 11 In the Code 11 style, there are three dark bars and two light bars for a total of five bars. Both light and dark bars are coded to define the character. A narrow light/dark bar is assigned a binary 0 and a wide light/dark bar is assigned a binary 1.
Codabar b/n Codabar b/n has four dark bars and three light bars for a total of seven bars. Both light and dark bars are coded to define the character. A narrow light/dark bar is assigned a binary 0 and a wide light/dark bar is assigned a binary 1. Codabar b/n has the following characteristics: • Character set includes ten digits (0 – 9) plus six characters (: / .
Codabar d/e Codabar d/e has four dark bars and three light bars for a total of seven bars. Both light and dark bars are coded to define the character. A narrow light/dark bar is assigned a binary 0 and a wide light/dark bar is assigned a binary 1. Codabar d/e has the following characteristics: • Character set includes ten digits (0 – 9) plus six characters (: / .
• Fixed length of seven characters per complete symbol. The first digit is the number system code, followed by six digits of data. The printer computes the check digit automatically and embeds it in the bar code as the eighth digit. All eight digits are encoded in the bar code symbol with four digits to the left of the CENTER code in odd parity, and four digits to the right of the CENTER code in even parity.
• If more or less than twelve characters are used, or if any of the characters used are illegal, an error message is printed. Interleaved 2 of 5 The bar code symbol uses a series of wide and narrow bars and spaces to represent numeric characters. The structure is 2 wide elements (bars or spaces) and 3 narrow elements. In the bar code, two characters are interleaved (paired); bars are used to represent the first character in the pair and spaces are used to represent the second character in the pair.
The above is always true except with the START/STOP and CENTER character codes. The START/STOP character bar pattern consists of two dark bars and one light bar for a total of three bars. The CENTER character bar pattern has two dark bars and three light bar for a total of five bars. Parameters P2 through P5 and P7 are not applicable and are ignored.
• START and STOP codes • No CENTER code • Intercharacter gap not definable • Fixed length of eleven digits per complete symbol. The first character of the data field is interpreted as the number system code and must always equal 0. The next five digits represent the vendor number and the last five represent the product number. • If more or less than eleven characters are used or if any of the characters are illegal, an error message is printed.
• The printer computes a modulus 10 checksum digit so that the six digits to be encoded in the bar code symbol are selected correctly. However, the check digit is not encoded as part of the bar code symbol and is not printed in the human–readable line. Table A–2. UPC–E Number Pattern Sequences If the Vendor Number is: Then the Encoded UPC–E Bar Code Symbol is: And the Product Number is: XX000 XX100 XX200 0 0 0 .0 0. . .. .. .. 00 999 X X 0. 0. 0. 0 X X .. .. .. 1 X X 9 9 9 2 XX300 . . .
Postnet has the following characteristics: • Ten digit character set (0 – 9) • Illegal characters are not processed and are ignored. • START and STOP codes • No CENTER code • Variable length characters per complete symbol • A checksum is calculated automatically then embedded at the end of the bar code. • The human–readable data field is not printed. Code 128 – USS Code 128 includes three character subsets: A, B, and C. (Code 128–UCC uses subset C only.
Data Field Code 128 bar codes support a full ASCII character set: Subset A provides standard alphanumeric keyboard characters, control and special characters; subset B includes all standard alphanumeric keyboard characters, lowercase alphabetical characters, and special characters; subset C provides 100 digit pairs, from 00 to 99 inclusive, plus special characters. Table A–3 lists the full Code 128 character set.
Automatic Mode The printer creates the shortest possible bar code by automatically sending the subset switch character to switch from subset B into subset C whenever strings of four or more consecutive numeric characters are detected in the input data. As long as the data includes ordinary keyboard characters and no subset switch, the printer switches in and out of subsets B and C automatically before and after numeric character strings.
Subset Switch Characters: Subset C: Subset B: >7>,>–>.>/ >576777879 >6lmno Non–ASCII characters are specified by using the subset switch characters (from >1 through >8 in the Alternate column on Table A–3) which corresponds to your application. The Value column is used when manually translating subset B and C bar codes into their briefest form. NOTE: The subset switch start codes, >5, >6, and >7 have two functions. At the beginning of a line, they start manual mode data in subset C, B, or A, respectively.
Subset A – Subset A operates in the manual mode only. Subset A data characters include mostly normal printable ASCII characters which require no subset switching and can be entered directly. For example, the data ABC123 in subset A is input in the bar code command as: ESC%0>7ABC123ESC%@. Switching to another subset will not generate a shorter bar code.

Code 128 Examples The following commands generate the horizontal default ratio Code 128 bar code below in the automatic mode. In the Start Bar Code sequence (DECBARC), SP represents the ASCII space character (hex 20). ESC[14;;;;;;;;2’q ESC%SP0ABC123456ESC%@ The following command generated the Code 128 bar code below in the automatic mode using data of 22446688ABC123456. The bar code data begins in subset B and automatically switches to subset C for the numeric data.
The command below generates the same vertical Code 128 bar code in the automatic mode, subset B. Because less than 4 consecutive numeric digits were provided in the data, no subset switching occurred, and the bar code remained in subset B. In the Start Bar Code sequence (DECBARC), SP represents the ASCII space character (hex 20).
Code 128 – UCC The 128–UCC Serial Shipping Container Code is a restricted subset of the Code 128–USS standard. It is used as a standard for labeling shipping containers. The 128–UCC Serial Shipping Container Code has the following parts: • Start Code – The 128–UCC Serial Shipping Container Code consists of numeric data only, so the start code is always Start–C. This is followed by the function code 1 character, which is part of the 128–UCC standard. These are automatically generated by the printer.

Density and Spacing Between Bar Codes The following subsections describe the spacing between different combinations of horizontal and vertical spacings between the bar codes. Horizontal Bar Codes (0 and 180 Degree Rotation) The width of a horizontal bar code is a function of the number of characters in the bar code symbol, the style of the bar code symbol, and the ratio of wide light/dark bars to narrow light/dark bars. The bar code height is specified as a parameter where the default is 0.75 inches.
Vertical Spacing Between Horizontal Bar Codes The vertical limit is equal to the maximum allowable height for a bar code symbol: 10 inches. If the human–readable line is printed, then a 0.1 inch gap plus character size is added to compute a total vertical distance. If the human–readable line is printed, a space the size of the intercharacter gap exists between the human–readable line and the top of the bar code symbol on the next line, plus any linefeeds you have specified.
paper. Therefore, if a line of input is rotated with the comma as the delimiter, the bar code symbols are printed one against another. You must use either the space character (20H) or the horizontal tab character (09H) to keep this from occurring. If a human–readable line is printed, its 0.1 inch gap is computed into the total horizontal distance. Vertical Spacing Between Vertical Bar Codes Vertical spacing is achieved via user–supplied linefeeds.

Print Rates The printing speed of text is a function of the selected font and dot density, and is measured in lines per minute (LPM). Print speed is independent of the number of characters configured in the character set. Text containing attributes such as bold or emphasized printing, superscripts, subscripts, or elongated attributes cause print rates to decrease to not less than half the rates of the font without such attributes. Table B–1 provides typical printing rates.

Introduction This appendix contains sample programs that illustrate how to use Digital control sequences and bar code control sequences in applications. Digital control sequences are described in Chapter 7, “Digital Emulation.” Bar code control sequences are described in Appendix A. NOTE: The print samples in this appendix were printed on an LG06 printer.
Figure F–1.
Bar Codes Bar code escape sequences determine the type of bar code, its attributes, and start and stop bar code printing. Bar code escape sequences are defined in Appendix A. The bar code examples in this section use the following escape sequences: CSIP1;P2; ... P9’q Select Bar Code Attributes (DECSBCA) ESC%SP0 Start Bar Coding (DECBARC) ESC%@ Stop Bar Coding Interleaved 2 of 5 The following command sequences create the bar code shown in Figure F–2.

Print Samples F–11
Figure F–7.
Glossary active column The horizontal location on the paper where the next character will print. After printing a character, the printer advances the active column. active line The vertical location on the paper where the next character will print. After printing a line, the printer advances the active line. active position The position on the paper where the next character will print. The active position is defined by the horizontal position (active column) and the vertical position (active line).
character weight The degree of lightness and thickness of printed text. For example: Bold refers to a heavy or thick character weight. Medium, normal, or book weight refer to the character weight used in this sentence. control sequence Two or more bytes that instruct the printer to perform a special function. A control sequence begins with the control sequence introducer, CSI, in an 8–bit data environment.
IA–232D Electronic Industry Association Specification: RS–232D interface that conforms to EIA standards. Elite A name indicating a monospaced font with 12 cpi pitch (and usually 10 points in height). Em A font width term equal to the maximum character width obtainable in a given font. (Derived from the width of an uppercase M, usually the widest character in a set.) emulation Refers to the ability of a printer to execute the commands of another printer language or protocol.
6) Character weight 7) Character proportion (normal, condensed, expanded). font name See typeface. font pattern A font pattern is the matrix of pels which represents a character, symbol, or image. font, landscape A font printed parallel to the long edge of a page, or a font capable of being produced on a landscape page orientation. font, monospaced Also called fixed–pitch fonts. Every character, regardless of actual horizontal size, occupies the same amount of font pattern space.
host computer The host computer stores, processes, and sends data to be printed, and which communicates directly with the printer. The term host indicates the controlling computer, since modern printers are themselves microprocessor–controlled computer systems. ipm inches per minute: The speed at which graphics are plotted. interface The hardware components used to link two devices by common physical interconnection, signal, and functional characteristics. See also Printer Interface.
OCR Optical Character Recognition is the process by which a machine reads characters printed in a special standardized font. Data are read by a photoelectric optical scanner and recorded on magnetic tape or disk. OCR–A and OCR–B are two widely used fonts. off–line The non–printing operational state of the printer. When the printer is off–line, communication between the printer and the host computer is temporarily stopped and the message “Off–line/Emulation” appears on the display.
Pica A name indicating a monospaced font with a pitch of 10 cpi and usually a 12 point height. Pica is also used in typography as a unit of measurement: 1 pica = 1/6 inch. pin configuration Establishes the physical attachment and protocol conversion connections for the host interface. pitch The number of text characters printed per horizontal inch. Specified in characters per inch or cpi. pixel Acronym of picture element or picture cell. Also called a pel.
said to be volatile because all data are lost when power is turned off or interrupted. Compare ROM read To retrieve data from memory or mass storage (hard disk, floppy diskette, RAM, etc.). reset To turn off, deactivate, disable, or return to a previous state. resolution A measure expressing the number of component units in a given range used to create an image; in printing, expressed as the number of dots per inch (dpi) horizontally and vertically.
serif A short line stemming from and at an angle to the upper or lower end of the stroke of a letter or number character. serif A set To turn on, activate, invoke, or enable. shadow printing A typeface with a heavy line thickness produced by doublestriking. The printer forms a character, then prints it again, but fractionally offset from the first position. See also bold, character weight. sixel A vertical column consisting of six pixels and treated as a unit in graphics applications.
weight See character weight. write A process in which data is placed (written) into memory or mass storage (RAM, hard disk, floppy diskette). X–off A character transmitted by the printer announcing that the printer is off–line or the buffer is almost full. X–on A character transmitted by the printer announcing that the printer is on–line or the buffer is almost empty.
