5-3-1. Test Printing

printer.

pressed. The printer will run a test print according to the Ver.
No., DIP switch settings, and memory switch settings.

Place the thermal roll paper on the printer.
Open the printer cover, then turn the power on while holding
the FEED button.
When the cover is closed, “*** HEX DUMP PRINTING
***” is printed, and the printer enters the Hexadecimal
Dump Mode.
Each of the signals sent from the computer to the printer will
be printed out in hexadecimal code.
This function allows you to check if a control code sent to the
printer by the program being used is correct or not. The final
line is not printed if its data is less than one full line.
However, if the FEED button is pushed, the final line is
printed. To turn off the mode, it is necessary to turn off the
printer completely.
