PSB No: P-0084A Page: 2 of 6 3. Q. What is the Epson ESC/P 2 command set? A. As the leading impact printer vendor, the Epson Standard Codes for Printers (ESC/P) has become a de facto standard for most dot matrix printers. Epson Standard Codes are featured by most other vendors as an immediate entry into a wide range of third party software. As the market continues to develop new requirements, Epson has moved to improve its standard by offering a version called ESC/P 2. 4. Q.
PSB No: P-0084A Page: 3 of 6 adjust the maximum number of lines per page. Decreasing the program’s maximum number of lines per page by 5 (e.g. 61 lines) should correct for this print position difference. 6. Q. Why is a ON-LINE/OFF-LINE or PAUSE button not present on the AP-3250’s front panel? A. The AP-3250 printer was designed to be as easy to use as possible. Because of this, the AP-3250 was designed any unnecessary buttons. The AP-3250 automatically goes into a ready condition after being powered on.

If a printer driver selection is not shown for the AP-3250 in my application software programs, which printer driver selection should I choose? A. The recommended printer driver selections for the AP-3250 are listed below in order from best to worst.
PSB No: P-0084A Page: 5 of 6 14. Q. Does the AP-3250 use DIP switches? A. No, the AP-3250 does not use DIP switches. The various features settings are selected through use of the two buttons on the printer’s front panel. 15. Q. Can the AP-3250 print on labels? A. Yes, the AP-3250 can print on labels.

PSB No: P-0084A Page: 6 of 6 20. Q. Why is the AP-3250’s parallel cable connector located on the side of the printer instead of the rear like most other printers? A. Since the AP-3250 may be operated in two different positions it was necessary to relocate the parallel cable connector to the side of the printer. 21. Q. Can different fonts be selected on the AP-3250’s front panel? A. Yes, different fonts may be selected from the AP-3250’s front panel by using the font button.
EPSON EPSON AMERICA INC. Product Support Bulletin Subject: Understanding and Using ESCP/2 Commands and Syntax PSB No: P-0082 Originator: JW Date: 12/4/91 Page(s): 1 of 14 This bulletin provides detailed explanations and illustrations for some of the more commonly used printer commands used in ESC/P2 Listed below are the commands discussed in this bulletin. Command Command Name ESC X m n1 n2 ESC ( C m1 m2 n1 n1 ESC(vm1 m2 n1 n2 ESC(Vm1 m2 n1 n2 ESCtn ESC ( t n1 n2 d1 d2 d3 ESC( ^ n1 n2 d1...
PSB No: P-0082 Page: 2 of 14 ESC X m n1 n2 (Select Pitch and Point Size) C X m n1 n2 is the command for selecting pitch and point size where m, n1 and n2 are variables. The variable "m" is used to select the pitch which is the character spacing. The variable "n1" selects the point size and the variable “n2”, at this time, will always be 0 (zero). The variables "m" and "n1" are explained below. The values used for ’m’ are 0,1,18,21,24,30,36,42,48,60, and 72.

PSB No: P-0082 Page: 5 of 14 ESC ( C m1 m2 n1 n2 (Set Page Length in Defined Units ESC ( C m1 m2 n1 n2 is the command for setting the page length in units where ml, m2, n1 and n2 are variables. The “unit’ is usually 1/360 of an inch unless defined otherwise by the “ESC ( U" command. Currently, the values for m1 and m2 MUST be m1=2 and m2=0. To determine the values for n1 and n2 perform the following steps. 1. Determine the desired page length in inches. 2 Multiply the page length by 360.
PSB No: P-0082 Page: 6 of 14 1 ESC ( v m1 m2 n1 n2 (Set Relative Vertical Position ESC (v m1 m2 n1 n2 is the command for advancing the print position vertically in units where m1, m2, n1 and n2 are variables. The "unit" is usually 1/360 of an inch unless defined otherwise by the “ESC ( U" command. Currently, the values for ml and m2 MUST be m1=2 and m2=0. To determine the values for n1 and n2 perform the following steps. 1. Determine the desired vertical motion distance in inches.
PSB No: P-0082 Page: 7 of 14 EXAMPLE 1. 2. 3. 4. 5. 6. The desired distance is 1/4 inch. 1/4 x 360 = 90 90 divided by 256 = 0 with a remainder of 90. 256-90=166 n1=166 n2=255 In the Basic programming language, the command would look like this. LPRlNT CHR$(27);“(v”;CHR$(2);CHR$(0);CHR$(166);CHR$(255) This command, as listed in the line above, will feed the reverse feed the paper 1/4 inch from the current line. The current print column (horizontal position) IS NOT changed.
PSB No: P-0082 Page: 8 of 14 C (V m1 m2 n1 n2 is the command for changing the print position vertically (with respect to the Top of Form position) in units where m1, m2, n1 and n2 are variables. The "unit” is usually 1/360 of an inch unless defined otherwise by the ”ESC(U" command. Currently, the values for m1 and m2 MUST be m1=2 and m2=0. To determine the values for n1 and n2 perform the following steps. 1. Determine the desired vertical distance from the Top of Form in inches.
PSB No: P-0082 Page: 9 of 14 ESC t n is the command for selecting a character table to be used for printing where n is a variable. The following table lists the values for n and the character table associated with the value. I n I I 3 I PC437 (US) T a b l e II II Table 1 NOTE: 1. Character tables other than those listed above can be assigned by using the ESC ( t command (Assign Character Table). 2 The value used for n can be either the ASCII value OR the ASCII character (i.e. chr$(1) or “1”).
PSB No: P-0082 Page: 10 of 14 ESC ( t n1 n2 d1 d2 d3 (Assign Character Table) ESC (t n1 n2 d1 d2 d3 is the command for assigning character tables where n1, n2, d1,d2, and d3 are variables. Currently, variables, n1, n2 and d3 MUST be n1=3, n2=0, and d3=0. Variable d1 is a number corresponding to one of the four tables selectable with the ESC t n command. This is the table that will be replaced. Valid values for d1 are 0,1,2, and 3 (see Table 1 below).
PSB No: P-0082 Page: 11 of 14 page contains a print sample of the Registered Tables available in printers sold in the U.S. In order to print the first 31 characters in Tables 1 through 9, the ESC ( ^ command must be sent. Listed below is a Basic language program and an explanation of the program that will print the output illustrated on page 13 of this bulletin.
PSB No: P-0082 Page: 12 of 14 60 If the Registered Character Table number is not 0, print ASCII values 1 through 255 inclusive. Remember, line 70 allows the first 31 ASCII values to print as characters, not control codes. 90 If the Registered Character Table number is not 0, do not execute commands in lines 100 and 110. 100 If this Registered Character Table number is 0, sand ASCII values 33 through 126 to the printer.
