I got my Thermal printer last week, and it was working fine.
But at some point, it stopped working and start random print characters, and the bitmap picture becomes dots.
I tried re-upload code and reopened, check all wires, nothing work.
Then I unplug and plug the printer again, suddenly, it works.
I have no idea what happened and want to fix the issue. I'm wondering if anyone could address the problem, or know what's going on here.

If the problem happens again, try the self-test before you unplug the printer.
