7156 Owner’s Guide Communication Communication Communication Overview In order for a receipt or slip to be printed, a program must be in place that translates the data from the host system into a language that the printer can understand. This program must tell the printer exactly how to print each character. This chapter describes how to create such a program or modify an existing one. Interface In order for the printer to communicate with the host, a communication link must be set up.
Communication 7156 Owner’s Guide Using DOS to Send Commands One way of getting commands to the printer is to send them directly from DOS. For example, the command COPY CON: COM1: sets the computer up such that the Hex code corresponding to any key that was pressed would be sent to the RS-232C communication port COM1 when the COPY mode is exited. If the printer is connected to COM1, then the data will go to the printer. Exit the COPY mode by typing CTRL Z and then pressing the ENTER key.
56 Owner’s Guide Communication XON/XOFF Protocol The XON/XOFF characters coordinate the information transfer between the printer and the host system. The printer sends an XON character when it is ready to receive data and it sends an XOFF character when it cannot accept any more data. The software on the host system must monitor the communication link as shown in the following flowchart in order to send data at the appropriate times. XON character = Hex 11. XOFF character = Hex 13.
Communication 7156 Owner’s Guide RS-232C Technical Specifications This section describes the pin settings for the connectors and the RS-232C interface parameters. The RS-232C parameters are selected by setting the DIP switches on the printed circuit board. See the illustration on page 16 for the position of the DIP switches. The RS-232C parameters must match those of the host. Connectors The following illustration shows the RS-232C communication connector and pin assignments.
7156 Owner’s Guide Communication The following illustration shows the pin out designation for the cash drawer connectors. The following table provides the pinout assignments for cash drawers one and two. The cash drawer connectors are located at the rear of the printer.
Communication 7156 Owner’s Guide Switch Settings The DIP switches are located on the PC board behind the front cover as shown in the illustration on page 16. They are used to set the RS-232C parameters as shown in the following illustration and table. These parameters must match those of the host system in order for the host system and the printer to communicate. Note: The switches can also be used for setting other functions and tests.

7156 Owner’s Guide Commands Set or Cancel Parallel Journal Printing Because there is no journal station on the 7156, this command is not implemented and is ignored if received. Hex Decimal ASCII 1B 7A n 27 122 n ESC z n Reverse Feed n Lines (Slip Station) Reverses the paper feed in the slip station by n lines at the current spacing. The next Character Feed command reverses the paper feed back to the normal feed direction.
Commands 7156 Owner’s Guide Journal Tab As there is no journal station on the 7156, this command is ignored as a tab command.
7156 Owner’s Guide Commands Single-Wide Characters Prints single-wide characters. Single-wide characters may be used in the same line with double-wide characters, but not in the same line with rotated charatcters or with single or double-density graphics. Hex Decimal ASCII 13 19 DC3 Rotated Print Rotates characters 90 degrees counterclockwise. The command remains in effect until the printer is reset or the Clear Printer (10) command is received.

7156 Owner’s Guide Commands Define User-Defined Character Set (Receipt Station) Defines and enters downloaded characters (for the receipt station) into RAM. It may be used to overwrite single characters. The user-defined characters are available until power to the printer is turned off, an Initialize Printer command (1B 40) is received, or a downloaded bit image (1D 2A) is defined. User-defined character sets for both slip and receipt may be used at the same time.
Commands 7156 Owner’s Guide Define User-Defined Character Set (Slip Station) Defines and enters downloaded characters (for the slip station) into RAM (this command is both an NCR 7150™ and an Epson TM-T80™ command).

Commands 7156 Owner’s Guide Disable Double Strike (Slip Station) Turns off the double strike mode on the slip station. Hex Decimal ASCII 1B 48 27 72 ESC H Select Character Code Table Selects the character set to be used. Code Page 437 and Code Page 850 cannot be used together on the same line. See Appendix A for both character sets.
7156 Owner’s Guide Commands Summary of Rotated Printing The table shows the combinations of Set/Cancel Upside-Down Print, Set/Cancel Rotated Print (clockwise), and Rotated Print (counterclockwise). Rotated CCW is mutually exclusive with the other two commands. The samples of the print show only the normal size characters. Double-wide and double-high characters are printed in the same orientation (double-high characters cannot be printed on the slip station). They may also be mixed on the same line.
Commands 7156 Owner’s Guide Station Select Commands These commands decide which station any incoming data will be printed on. Select Receipt or Slip for Printing, Slip for MICR Read Selects the station for printing. If a slip is present and the station selected changes from slip to receipt, the slip is ejected. If the station selected changes from receipt to slip, the printer waits for a slip or check to be inserted, either for printing or for reading the MICR characters.
7156 Owner’s Guide Commands Select Receipt Station Selects the Receipt Station for all functions. The receipt station is the default setting after the printer is initialized or the Clear Printer (10) command is received. If a select command for one station is followed by a select for another station with no data sent for the first station, only the second station will be selected. Note: This command is identical to Journal Tab (1E), an Epson TM-930™ command.
Commands 7156 Owner’s Guide Graphics Commands These commands are used to enter and print graphics data. Set Absolute Starting Position Sets the print starting position for graphics on the receipt station at the specified number of dots from the beginning of the line as expressed in the following formula: n = ((n1 + (256 x n2)) x 2). The resulting dot column must be less than 448. The print starting position is reset to column one after each line.
7156 Owner’s Guide Commands Set Bit Image Mode Sets the print resolution and enters one line of graphics data into the print buffer. Excess data is accepted but ignored. Any print command is required to print the data, after which the printer returns to normal processing mode. See the illustration on the next page for a graphic representation of the bit image. Hex Decimal ASCII 1B 2A m n1 n2 d1...dn 27 58 m n1 n2 d1...dn ESC : m n1 n2 d1...dn Receipt Station Value of m 0 1 32 33 Mode No.
Commands 7156 Owner’s Guide Single-Density Graphics This NCR 7150™ command is not available. Use Set Bit Image Mode (1B 2A) described on the previous page. The Hex code, 1B 4B, is used for an Epson command, Print and Reverse Feed n Mininimum Units (1B 4B n).
7156 Owner’s Guide Commands Double-Density Graphics Enters one line of 8-dot double-density graphics into the print buffer. Excess data is accepted but ignored. Any print command is required to print the data, after which the printer returns to normal processing mode. Double-density mode allows 0-448 dot columns on the receipt, 0-660 dot columns on the slip. The number of bytes sent is represented by the formulas in the second table. Each bit corresponds to one horizontal dot.
Commands 7156 Owner’s Guide Value of n1 Value of n2 Value of d Bytes of Data (Printed 1-56 (8 x n1 = Number of 1-48 (Number of Down Then Across) Horizontal Dot Columns) Vertical Bytes)* *The number of bytes sent is represented by the following formula: n = 8 x n1 x n2 (n1 x n2 must be less than or equal to 1344). Column Top of Graphic One Column 56 x 8 Max. Row One d1 d 49 d2 MSB dn Row 48 d Max.
7156 Owner’s Guide Commands Printer Status Commands These commands enable the printer to communicate with the host system following the selected handshaking protocol, either DTR/DSR or XON/XOFF. They are stored in the printer's data buffer as they are received, and are handled by the firmware in the order in which they were received. When a fault occurs, the printer will go busy at the RS-232C interface and not respond to either of the Printer Status commands.
Commands 7156 Owner’s Guide Transmit Printer Status Sends status data to the host system. Hex Decimal ASCII 1B 76 27 118 ESC v The printer sends one byte to the host system. See the table below. In DTR/DSR protocol, the printer waits for DSR = SPACE.
7156 Owner’s Guide Commands Real Time Commands These commands correct difficulties with the original version of the 7156 RS-232C communication interface: • Real Time Status Transmission (GS Sequence and DLE Sequence) • Real Time Request to Printer (GS Sequence and DLE Sequence) • Real Time Printer Status Transmission The original Printer Status commands, Transmit Printer Status (1B 76—ESC v) and Transmit Cash Drawer Status (1B 75 0—ESC u 0) are placed in the printer’s data buffer as they are receive
Commands 7156 Owner’s Guide An application using these DLE sequences must also send the second byte of the sequence within 100 milliseconds of the first, to prevent the first byte being mistaken for a Clear Printer command. This implementation is useful for an existing TM-T85™ or TM-U950™ application which is being migrated to a 7156. This application would not be using the 7156 Clear Printer command at all since it is not recognized by the Epson printers.
7156 Owner’s Guide Commands Although the printer responds to real time commands when it is busy, it will place them into the buffer behind any other data there, and flush them out in the order in which they were received. When the printer is busy due simply to buffer full (that is, it can’t print data as fast as it can receive it), then data continues to be processed out of the buffer at approximately print speed and the real time commands will eventually get flushed out.
Commands 7156 Owner’s Guide Hex Decimal Value of n ASCII 1 = Transmit printer status 2 = Transmit RS-232C busy status 3 = Transmit error status 4 = Transmit receipt paper status 5 = Transmit slip paper status The command is ignored if n is out of range. 10 04 n 16 4 n DLE EOT n Note: An application using the DLE sequence must send EOT within 100 milliseconds of DLE or the printer will misinterpret the DLE and execute a Clear Printer command.

Commands 7156 Owner’s Guide Real Time Request to Printer The printer responds to a request from the host specified by n. The operations performed depend on the value of n, according to the following parameters. GS Sequence Hex Decimal ASCII Value of n 1 = Recover and restart 2 = Recover and clear buffers 3 = Cancel slip waiting The command is ignored if n is out of range.
7156 Owner’s Guide Commands If the slip is selected, this command will attempt recovery from a slip motor jam by rehoming the printhead and waiting for a slip to be inserted before restarting the print. Other errors associated with the slip, such as cassette door open, can be recovered from only by clearing the specific condition, such as closing the cassette door. n=2 Recovers from an error after clearing the receive and print buffers.
Commands 7156 Owner’s Guide Real Time Printer Status Transmission Transmits one byte status of the printer in real time.
7156 Owner’s Guide Commands Recognizing Data from the Printer An application sending various real time and non-real time commands to which the printer responds can determine which command a response belongs to by the following table. Note that a response to GS EOT n or DLE EOT n cannot be distinguished from ASCII data coming from a MICR read. While MICR data is still outstanding, an application should use the real time GS ENQ.
Commands 7156 Owner’s Guide Bar Code Commands These commands format and print bar codes on the receipt station. Select Printing Position of HRI Characters (Receipt Station) Prints HRI characters (Human Readable Interface) above or below the bar code.
7156 Owner’s Guide Commands Print Bar Code (Receipt Station) Selects the bar code type and prints a bar code for the ASCII characters entered. Hex Decimal 1D 6B 29 107 n c1 c2...00 n c1 c2...00 00 = End of command. ASCII Value of n Value of c GS k n c1 c2...
Commands 7156 Owner’s Guide Print Code 128 Bar Code (Receipt Station) Selects and prints the Code 128 bar code. Hex Decimal ASCII Value of n Value of dn 1D 6B 49 n dn 29 107 73 n dn GS k I n dn 1-255 0-105 Since the characters encoded via Code 128 include the NUL (0x00) character, a NUL cannot be used to terminate the Code 128 bar code sequence as is done with other bar code sequences. The number of characters to be encoded is variable and is specified by n. Following n are the data bytes: dn.
7156 Owner’s Guide Commands MICR Reader Commands These commands control the Magnetic Ink Character Recognition (MICR) Reader, including how it parses the character strings on checks. The remainder of this chapter explains these commands. The section that follows, “MICR Parsing,” describes how to create a parsing format and how to create and maintain an exception table.
Commands 7156 Owner’s Guide Hex Decimal ASCII 1B 77 70 parameters 27 119 112 parameters ESC w p parameters MICR Parsing This section describes the MICR parsing in more detail and includes several examples of useful parsing variations. It also describes how to create a parsing format and how to create and maintain an exception table.
7156 Owner’s Guide Commands Variable Length Field Optional Modifiers Selector Comments Zero fill to length 0 Maximum length Remove space/dash Replace space/dash with 0 nn X x ASCII zero preceeding maximum length 1- or 2-digit ASCII number Examples of Variable Length Field Format Specifications Account #, all characters in the field, keep spaces and dashes Account #, all characters in the field, replace spaces and dashes Account #, maximum 12 characters, keep spaces and dashes Account #, always 12
Commands 7156 Owner’s Guide Field Separator 'x Field separator preceded by a single quote, so a field separator of the letter A would be sent as 'A (0x27 0x41). If a Carriage Return is specified as a separator (0x27 0x0D), a final Carriage Return must still terminate the parsing parameter string.
7156 Owner’s Guide Commands Sample Parsing Formats The following strings show various sample formats that you can use assuming they meet your parsing format needs. Included with the sample format is a description of the data that is returned to the application.
Commands 7156 Owner’s Guide ESC w p T 18 X A 04C • All characters in the transit number • All characters in the account number (up to 18) with spaces and dashes removed • Always four characters in the check number (zero-filled if check number is only three characters long) • Final Carriage Return ESC w p K9 X T 18 X A 04C • U.S.
7156 Owner’s Guide Commands Notes All parameters are ASCII characters, i.e. greater than or equal to 0x20, with the exception of a non-ASCII character enclosed in single quotes as a field separator. This applies both to parameter specifications sent from application to printer, and to MICR data returned from printer to application. Parameters are positional; their order in the parameter string is the order in which the parsed MICR data will be returned.
Commands 7156 Owner’s Guide Once a parsing format is specified, the following values are returned: MICR Characters ASCII Hexadecimal Numerics 0...9 0x30...0x39 Space 0x20 Dash 0x2D Field separator* Country code* *As specified in the parsing parameter string With RS-232C communication, the printer adds a final carriage return to the MICR data sent to the application. Check Serial Number Parsing the Check Serial Number Most banks print the check serial number in three easily recognizable spots.
7156 Owner’s Guide Commands If both of these searches fail to produce the check serial number, extract the whole account number field from between the rightmost transit symbol and the rightmost “on us” symbol. A three, four, or five digit number to the right of the rightmost transit symbol, separated by a space or a dash from the rest of the account number is the check serial number.
Commands 7156 Owner’s Guide Loading the Exception Table The exception table begins at word 20 in NVRAM. Each entry takes five words. There is room for eight exceptions with a sumcheck written in the last word. An application can load local exceptions into the printer using the write NVRAM command: 0x1B 0x73 n1 n2 k which writes the two byte word n1:n2 to word k in NVRAM. Exception Table Entry Format Each exception table entry consists of five words.
7156 Owner’s Guide Commands Example 1 t123456780t12349876543210o 1234 is the check serial # 9876543210 is the account # To load the second table entry, which starts at word 25, the transit number 123456780 would be stored in the first two words of its table entry using this string of commands: 0x1B 0x73 0x12 0x34 25 0x1B 0x73 0x56 0x78 26 After the right transit symbol are immediately the four characters of the check serial #, followed immediately by the ten characters of the account number.
Commands 7156 Owner’s Guide 0x1B 0x73 0x84 0x47 32 0x1B 0x73 0x82 0x24 33 0x1B 0x73 0x00 0x00 34. Maintaining the Exception Table Present contents of the exception table can be examined using the read NVRAM command: 0x1B 0x6A k which reads and returns word k in NVRAM. When the exception table is full, a new entry can replace an older, less frequently used entry, by merely rewriting the words for that table entry.

A756- 8xxx new commands and features User accessible flash memory Description The A756-8xxx provides two 64K pages of non-volatile flash memory that are user accessible. The advantage of flash memory is that when written, the contents are preserved over a printer power cycle. Flash memory remains intact until it is erased. Flash memory can be written one byte at a time, but it cannot be erased one byte at a time: an entire 64K page must be erased at once.
A756- 8xxx new commands and features Identification of flash The existing Transmit Printer ID command will tell an application that the printer connected is the A756-8xxx, with flash memory: GS I n Transmit Printer ID.
A756- 8xxx new commands and features Erasing flash GS @ n Erase flash. format ASCII Hex Decimal range 49 ≤ n ≤ 50 GS 1D 29 @ 40 64 n n n The printer erases a page of flash and sends a Carriage Return (0x0D) when the erase is complete. n = 49 (ASCII ‘1’ only) This command will erase the entire 64K page available for user-defined characters and multiple logos.
A756- 8xxx new commands and features Multiple logos GS # n Select active logo. format ASCII Hex Decimal range 0 ≤ n ≤ 255 GS 1D 29 # 23 35 n n n This command selects a logo to be defined or printed. The active logo number n remains in effect until this command is sent again with another number n. When this command precedes a logo definition, that definition will be stored in flash memory as logo n.
