Up for sale is an Atari 820 printer. This item is in good physical condition with no damage to the plastics, just a little dirty and could use a good bath. There is a number etched into the bottom of the printer (see picture), but since it is on the bottom, you don't see it in use.
I have connected this 820 printer to a 600XL and was able to print a test message. The original ribbon barely as some life left in it! So the printer does appear to be working just fine. No additional testing was performed. If you'd like me to test something specifically, please let me know!
Printer comes with the original manual (which is unbound and has punch holes on the left for a binder) and an SIO cable that has seen better days, but works.
