HP 82143A Printer Self test?

[Kostas Kritsilas]

Diego,

Thanks for taking the time to reply. I tried the printer by connecting it to one of my HP-41CXs, and it printed. The printout looks fine, it is clear and the contrast does change when I move the slider, and the paper advances smoothly. I just wanted to print out the full character set to make sure everything is 100%.

I don't have any of those modules, nor do I have a CL. But I do know where to find the Printer Service Manual, so I will go get it from there.
