3-12 Application Development Information Rev. A
3.6 Bar Code Printing
This printer can print the following types of bar codes:
UPC-A, UPC-E
JAN 8 (EAN 8), JAN 13 (EAN 13)
CODE 39
ITF (Interleaved 2 of 5)
CODABAR (NW-7)
CODE 93
CODE 128
PDF417 (2D code )
QR Code
To set and print each bar code, refer to the OPOS, Advanced Printer Driver, and ESC/POS
command documentation, respectively.
Note:
Take a consideration as described below to determine whether the ability of the reader (scanner) can be
satisfied when the print result on the receipt, such as bar code, 2-dimensional code, or characters.
• Print density
The print density may vary depending on the type of roll paper or the environmental
conditions.
3.7 Notes on Printing 2-Dimensional Code
The TM-T70 supports 2-dimensional code printing. Be sure to follow the notes below when
printing 2-dimensional codes.
1. Provide the quiet zone according to the code specifications by the user.
2. When printing PDF417 (2-dimensional code), it is recommended to set the height of one
module of the symbol to three to five times the width of one module, also making sure that
the total height is almost 5 mm {0.20"} or more.
The recognition rate of the ladder bar code or 2-dimensional code may be affected by such items
as different widths of the modules, print density, environmental temperature, type of the
thermal paper, and characteristics of the reader. Therefore, the user should check the recognition
rate in advance so that the limitations of the reader can be considered.
3.8 Operating Mode (Switch Panel Operation)
The printer has a self-test mode to check printer settings in addition to the regular print mode.
3.8.1 Self-test Mode
In the self-test mode, the following items are checked and printed out:
• Control circuit functions
