Bar codes
These commands format and print bar codes and are described in order of their hexadecimal
codes, with the exception of the QR code overview, which is described in the order of use in
creating two- dimensional QR codes.
These commands describe operation for 80mm paper.
QR code Overview
QR code is a 2-dimensional matrix symbology consisting of an array of nominally square modules
arranged in an overall square pattern using the QR symbology. A unique pattern at three of the
symbol’s four corners assists in determining the bar code size, position, and rotation.
A series of six commands are required to create and print QR codes.
1.
Select model for QR code
1D 28 6B 04 00 31 41 n1 n2
2.
Set the size for QR module
1D 28 6B 03 00 31 43 n
3.
Set data parsing mode
1D 28 6B 03 00 31 44 m
4.
Select error correction level
1D 28 6B 03 00 31 45 n
5.
Store symbol data
1D 28 6B qL qH 31 50 30 f1…fk
6.
Print symbol data
1D 28 6B 03 00 31 51 30
The details of each command are described below.
Note: The settings for model, size of module, and error correction level are effective until the
printer is reset, or the power is turned off.
Select model for QR code

1D 28 6B 04 00 31 41 n1 n2
29 40 107 4 0 49 65 n1 n2
31h = Selects model 1
32h = Selects model 2 (default)
Value of n2:
00h (default)
This command specifies the original version (m = 1), or the enhanced form of the symbology (m =
2). Model 2 is the recommended model.
