Bipolar Stepper Motor

Posts: 35
Hi everybody.
I am very new in stepper motors so if please don't laugh at me if i am asking silly questions...
I have lots of stepper motors from printers so i decided to build something.
I am using parallel port ( printer - 25 pin ) to control the step motor. I used CVI to send pulses to uln2003 in order to control unipolar stepper motor but i don't know how to control bipolar and what i need!
Please help me...
Thanks.

forum rules prohibit people from posting the same question on different forums. However, you can request a moderator to move a posting to a different forum. I think the way to request attention from a moderator is to go back to the forum you want to move, click on the little triangle with the exclamation point in it, and report what you want to do.
today i tried to make unipolar motor work but nothing happened
i wired the motor to uln2003 and sent pulses from pc. I put leds to check if pulses were working and check the voltage and both of them were good. What can be the problem???
I'm confused. Are you trying to work with a bipolar stepper motor? If so, I don't think the uln2003 can work with bipolar steppers.
I think i made a mistake!!
Motor has 5 wires but when i check the resistance with voltmeter i got results only with 4 of them. I guess It is bipolar so because of this it didn't work...
The thing is i datasheet of the motor it writes that it is unipolar!!!
What do u think?
Motor is : Mitsumi M35SP-9T
