Hi,

I want to learn to program the parallel port in Windows. The language can be VC++ or VB. I think I will use the Win32 APIs.

But the problem is, I don't have any parallel port devices attached to my PC. Not even a printer...

Any suggestions how I may go about this ? Or, do I have to buy a device, a printer or something ?

Regards.

try buiding this one, it has LEDs that indicates data pins status from LPT of your PC
And heres some links for some tutorials:

Hi budhy,

thanks for the download.

Actually I was wanting to use the Win32 APIs, like DeviceIOControl, ReadFile and WriteFile, with the Parallel Port.

If you could please elaborate how to use your Parallel Port Manipulator to monitor the output of these API calls.

Regards
