I'm having flashbacks to an old epson stylus printer from the early 90s...
If that is what the motors came out of then they are hybrid steppers (unipolar or bipolar) and run on 0.5 Amps and 12 Volts. They were low torque and maybe 4.8 degrees per step. I doubt that you are going to find a data sheet online for them because of their age, but a little work with an ohm meter and you can probably create your own.
