APPENDIX H: NOTES ON PRINTING 2-DIMENSIONAL CODE
The TM-T81 supports 2-dimensional code printing.
Be sure to follow the notes below when printing 2-dimensional codes.
•
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 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.
APPENDIX I: NOTES ON SCANNING THE PRINT RESULT ON THE
RECEIPT
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.
1) Print density
The print density may vary depending on the type of roll paper or the environmental conditions.
2) Slant of the print result
The print result may be slant slightly as shown in Figure I-1. The slant angle of the print result is
within
±
1.6
°
and it varies while printing or each receipt issue.

NOTE: In case that the paper other than the paper described in Section 1.5 Paper Specification is
used or when the paper is used out of the range in Section 1.12 Environmental conditions,
the print density or the slant of print result may become widen.
