parallel port communication

How do you output pulses to the parallel port and read pulses from the parallel port?

We are trying to control stepper motors and read encoders.

Working with the PC Parallel port is a little bit complicated using pure code.
There are some Dynamic Link Libraries (DLL's) and custom controls that enable easy access to this port as well as to the PC COM ports and any other USER port.
I can send you by e-mail a sample project that uses a DLL to access these ports. Just comment me your e-mail address.
