Appendix E
EPSON LQ 2550, ESC/P2, and Barcodes Quick
Reference
This appendix contains basic information on the EPSON LQ 2550, ESC/P2, and
EPSON Barcodes Printer Emulation:
Characters used in control functions appear in monospaced type. Table 1
explains some of the conventions used.
A pair of numbers separated by a slash ( / ) character indicates Column/Row
notation. This notation refers to the location of a character in a standard code
table, such as ASCII. (example: 1/B = 1B is the hex-code for Escape)
Spaces appear between characters in sequence for clarity; they are not part of
the format.
At the end of this chapter you will find a listing of the EPSON LQ 2550, ESC/P2,
and EPSON Barcodes Emulation commands classified by Hex Code and a Hex-
Decimal conversion table.
The following conventions are used in the command listings:
Table 1 Conventions
ESC Escape (1/B), introduces an escape sequence
P1 Numeric parameter, or number of units that specify a distance or
quantity pertaining to the escape sequence, control function or control
string. Accepted values are 0...9999, may be preceded by + or -.
If the parameter is in normal notation like "200" the programming in hex-
code is according to a ASCII table. ("200" = 32,30,30 in hex).
If the parameter must be programmed in hex-code the notation is with a
slash. (1/A = 1A in hex-code)
v1...vn A series of parameters pertaining to the escape sequence, control
function or control string.
SP Is standing for Space (hex 20)
