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 0–255.

• n L , n H specify 1 word (2 bytes) parameter as (n L + n×256) in the range

0–65,535.

• p L , p H specify the number of parameters after p H as (p L +p H ×256) in the range

1–65,535

• p1, p2, p3, p4 specify the number of parameters after p4 as

(p1+p2×256+p3×65,536+p4×16,777,216) in the range 1–4,294,967,295.

• kc1, kc2 specify key code (2 bytes) of NV graphics or download graphics. Each range of kc1 and kc2 is 32–126.

• Control codes are as follows: name code
