Now you can get the HobbyCNC Board which these motors work real well with, the instruction also has the right color wire coordination for them.
I would sugest you use a min. of 24v, but I wired three computer power suplies together in series with floating ground and got 33.6volts with 8 amps (amps are limited to the lowest amperage of power suplies, so if you have two 10a power suplies and one 8 amp then your end result will be 8 amps which is pleanty for these motors rated at 1.4a each. If you need help just let me know, I wish i was into this when i was your age.

Laserjet IIp and Laserjet IIIp aren't worth the effort. The motors in them are a Canon PM60-H418Z21B motor which I can't find any information on. Its a uni-polar stepper (6 wires) but the body is a non-standard size.
