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
Pn
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)
