Hey Terramir,
Chances are that you will find the driver right on the printer board. IC
L293D is an H Bridge that you could by:

Good luck

Subject: RE: [Electronics_101] How do I test a stepper motor
well on a first note I watch the video and it helped I could verify that
there were to continuous coils 6 to 9 ohms depending on the stepper motor.
As for the H bridges I didn't quite know what to make of that but all three
stepper motors had a coil between 1 and 3 and 2 and 4 and if I applied power
between 1 and 3 it snapped to the next step also the same with two and four
it then locks in that position.so would you guys say they all work?terramir

Hi Terramir,
Normally, 4 wires stepper are bipolar motors. If so, you will need H Bridge
Stepper Driver. Just Google it. He is a good page on the difference.
