APPENDIX I: NOTES ON PRINTING 2-DIMENSIONAL CODES
The TM-T90 supports 2-dimensional code printing.
Be sure to follow the notes below when printing 2-dimensional codes.
1) When printing PDF417 (2-dimensional codes), 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 {0.2"} or more.
2) The recognition rate of the 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.
