Not really related. In the early 2000s I bought a Star NL-10 dot matrix
impact printer from Micronics to my Linux box, which I shot at the local
flea market for $5. It didn't take five minutes for the landlord, who
lived in the same building (which is already bad in itself ;-) to knock
at the door and ask WTF am I doing. *g* If it was 20 years earlier (the
80s) no one would had cared about the noise it produced. But it was fun.

Btw. I have forgotten how I get it running. The PC then had a parallel
port and it seems Linux just served the printer right.

I have no real hardware, only emulate the C64 and Amiga. I once tried to
print from The Print Shop from the C64 to the Linux host via CUPS the
emulator (VICE) runs on. But I set it up wrong and the result was messed
up 50% of the time, the other 50% the emulator crashed when printing.
