This sounds like a machine I used to work on.
PDP-8/a, two floppy
drives, a VT-50 terminal that looked like it could have been provisioned
for an internal thermal printer, and ours had a LA-36.
Yep... they sold a bunch of them. The printer inside the VT-50 case
wasn't thermal, BTW. The "1976-1977 pdp-8/a minicomputer handbook" calls
it an "electrolytic copier" under the entry for the VT-61. My memory of
working with them was that they used funky paper and there was a wet
wiper brush that moistened the paper as it exited the printer. Perhaps
it squeegeed it. I don't recall any more.
That sounds like a Versatec printer, which used an electrostatic process
to attach the carbon suspended in the liquid toner...
