CNC control from a laptop

I've put this in ideas cos I'm not sure where it fits, but the project itself is still in the ideas phase so i think it's ok :D

Basically I'm slowly assembling parts and designs for a CNC milling machine, the usual xyz stepper motors with router on top sort of thing.

What I'd like to know is if it's possible to control it from a USB-parallel converter, I've read some things about the interpreting speed not being up to it (All I have at the moment is a laptop, so no parallel port)

Question: Turn on a pin on a parallel port

I need a program to control a pin on the parallel port.

It need to work on windows xp and it needs to turn only one pin on.

The idea is to turn port D1 on with program: Pport1 for example

and D8 with an other program

so that with my project with voice control I just need to start the program with the voice control softwareto turn the port on.
