4.8 Precautions for Two-Dimensional Code Printing

This printer can print two-dimensional codes. The following two-dimensional codes can be printed.

❏PDF417

❏QR Code

❏MaxiCode

Note the following for two-dimensional code printing.

❏The two-dimensional code recognition ratio changes depending on the module width, print density, environmental temperature, roll paper (thermal paper) type, reader performance, etc. Therefore, pre-check the recognition ratio and set the operating conditions to satisfy the restrictions of the reader.

❏For PDF417 (two-dimensional code) printing, it is recommended to set the height of one symbol to three to five times greater than the module width. It is also recommended to set the overall height of the code to more than 5 mm (approximately).

4.9Two-Color Printing

This printer can print two colors. For the two-color printing method, refer to the corresponding data of OPOS, Printer Driver, or ESC/POS commands.

Note:

Depending on the print pattern, the colors of two-color printing may not be clear (Example: Red and black checkered pattern). In this case, the print result may be improved to some degree by setting an unprinted space between the first and second colors or by adjusting the print density. (The amount of space depends on the print density and paper.)

The reliability of two-color printing differs from that of single-color printing. Refer to “Reliability” on page 6-5for details.

4.10 NV Memory

NV memory is embedded in the printer. Please use NV memory with attention to the following:

❏The following restrictions apply when performing nonvolatile memory operations (including data store and delete).

•The paper feed switch must not be used to feed paper.

•The real time command must not be executed.

•The ASB status will not be sent, even when the ASB function in ESC/POS command is set to enable.
