82162A Thermal Printer repair info

[4ster]

Yesterday I tried to print a file and the printer kind of puked.

It tries to print but struggles to print a faint line and then locks up with a low buzz that sounds like a struggling motor. The calculator screen displays "printer error".
The battery is charged, showing 5.4 volts.

Are there any resources available like there is for card reader repair? I was able to fix my card reader using help offered on a couple of different web pages. So far I have not located anything covering repair of little thermal printer. I'm willing to tear into it blind, but I know the outcome would be better if I have a little tribal knowledge beforehand.
