How to control a servo using my parallel port?

[ichweiss]

My problem is that I need to control a servomotor through my parallel port using labview, I tried to send alternated pulses (0,1) with a delay produced by a for loop but it is very unstable, please if anyone know a better solution to this let me know.

Thanks in advance.

Here are several examples on using LabVIEW with the parallel port:
