2.6 Self-testing
The self-test can detect whether the printer is working properly. If the self-test spline can be
printed correctly, it means that the printer is normal except for the interface with the host,
otherwise it needs to be repaired.
The self-tests are printed out in order: manufacturer name, printer model, software version,
interface type, default value of printer parameters, 96 characters in ASCII code, default code
page content (language setting in English) or Kanji library name ( If the language is set in
Chinese), the barcode type.
Self-test method is to hold down the [FEED] key and turn on the power switch, then the printer
