I'm attaching a picture of the printer, and and a paper that it printed with the self-test.

It might be kind of hard to see, but for some weird reason it's actually printing characters twice. You can especially see it on the last line, where it prints "H I J K L N O P" and it prints them twice, one on top of another. At first I thought it was some kind of mechanical problem, that maybe the pins in the print head weren't aligned right or something. But then when I looked at the paper more closely I realized that it is printing distinct characters, but it's just printing them twice vertically for some strange reason. The problem seems to be electronic, not mechanical.

Any idea what could be causing this?
