Stepper circa 1983

I dismantled two Commodore dot matrix printers that were in the trailer, circa 1983, and one of them had an 18 volt stepper motor, there were some fuses labeled 1.6 amps, so I'm guessing that this stepper should handle 1.5 amps or so. There were also servo motors complete with attached encoder wheels, though there is a gap in the holes, I think that the paper advance would spin the motors one revolution and that was geared down to match the right distance. The other printer used a veritable tangle of wires, springs and gears to position the carriage with a solenoid instead of a stepper.
