Parallel Port Control Made Easy - parashell allows control of a PC parallel port (input and output) with simple command line arguments. The simplicity of these programs make it very easy to use in scripts. Control stepper motors, Relays, LEDs, etc...
This is a test program that I created to learn how to control a stepper motor. It can be used to create a plotter (printer) but will eventually be used to manufacture parts for my home workshop as a plotting plasma cutter.
