ESC/POS Quick Reference

ESC/POS

Command System
EPSON ESC/POS is a proprietary POS printer command system based on the
escape sequence and includes patented or patent pending commands. ESC/POS is
compatible with most type of EPSON POS printers and displays.
ESC/POS is designed to reduce the processing load on the host computer in POS
environments. It comprises a set of highly functional and efficient commands and
also offers the flexibility to easily make future upgrades.
Aim of the Quick Reference
Quick Reference is a guide to using ESC/POS command to control the printer.
Command Notation
RT : real-time command (executed as soon as received)
fn= : function number of the command
Numbers are written in decimal numeral.
n specifies 1 byte parameter in the range 0255.
nL, nH specify 1 word (2 bytes) parameter as (nL+ n256) in the range
065,535.
pL, pH specify the number of parameters after pH as (pL+pH256) in the range
165,535
p1, p2, p3, p4 specify the number of parameters after p4 as
(p1+p2256+p365,536+p416,777,216) in the rage 14,294,967,295.
kc1, kc2 specify key code (2 bytes) of NV graphics or download graphics. Each
range of kc1 and kc2 is 32126.
Control codes are as follows:
name code
NUL 0
