So that my old machines have a printer they can talk to (and to remind myself why laser print is such an improvement over dot matrix) I bought a Smith Corona D-200 Dot Matrix printer on Ebay. Cost: about $50 shipped.
Notes:
Manual
The manual is here: "https://archive.org/details/manual_202302"
It's not a great manual. There's no troubleshooting. There's no spec for the printer cartridge. Not even a model number.
Ribbons
Ribbons for the thing seem to be specific to this model and unobtanium. My ribbon is in decent condition given its age, and will probably work well enough with some WD40 or mineral oil. Old trick from long ago. If you find a source for NOS or compatible ribbons, do please let me know.
Self Test Weirdness
Self test won't work without paper loaded. If the online led is flashing, it means you're detecting an out of paper event. Unless the dip switches are set to ignore it, this will stop the printer from self-testing.
Self test does not override IBM mode's linefeed settings. If your printer is in IBM mode (SW2 switch 1 on) the meanings of all the SW1 switches are different, and SW1 switch 2 (I think) can block your printer from linefeeding during selftest.
I turned off IBM mode, and my printer now linefeeds like a champ.
I'll post more as I know more.
