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.

Figure I-1 Slant of the Print

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.
