Turbo CNC will allow you to define pins on the parallel port to
control up to 4 (or more) motors with step/direction. The parallel
port will control all the motors.

I would recommend an isolator board to protect your computer.

My own particular design uses 3 separate driver boards, and a common
power supply with an isolator board.
