1. Self-checking of 58mm Receipt Printer

Self-checking can test the printer is work well or not, if it can print the test  list correctly that means the printer is good enough (which is excluding the problem with the connected interface to PC); otherwise, it needs repair.

Self-checking could print software version number, print density, interface type, English character and some Chinese characters by order.

Self-checking procedure: Make sure the printer is connected to the power, then press the feed key and switch on the power supply while the  key is still under pressing. At the same time, the printer begins to self-checking. Please loosen the  key within five seconds and the printer would print the self-testing list after it.

The test list looks like the following when it finished:
