Do you need to print on multi-part carbon or NCR forms? Do you need a dot-matrix impact printer?
I have a Star Micronics SB-10 dot-matrix impact printer. It has a parallel interface. My late brother was using it so I assume it still works. None of my computers have a parallel port so I can't test it. Printer, cable, manual, spare ribbon, original shipping packaging. If you want it, it's yours for the price of a PDF shipping label, 20" x 20" x 10" 30 pounds.
