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.
