controlling a stepper motor?

I've blown up several printers for scrap metal and parts and I do have a pile of assorted motors. Nearly all of them has 4 wires but I'm not quite sure how to drive it. How is a stepper motor controlled with 4 wires?

TIA

Try google. The Wikipedia description looks pretty good to me.

Specifically, Google for "bipolar stepper motor".

looks like a good reference.
