This simple program allows you to test the inputs and output pins on a parallel port. Unlike many other alternatives, this program will work perfectly with newer versions of Windows and should correctly detect parallel ports at non-standard addresses. Simply choose your parallel port, and then click pins to toggle outputs and watch the screen to monitor inputs.
Windows Server 2008
