Does your OS give you direct access to the port? Some do not. Have you posed this question in the microcontroller forum. Maybe get a better response?
 
hi bhargavraj patel,

If you are using Windows XP, you will probably require the 'inpout32.ddl' in your windows/system directory.
You can download a free copy from the web.

If you require a copy of my parallel port test program, let me know.
You will also require the Visual Basic runtime files from the web.

Hi,
The programs have been sent to your email address.
I would advise you to edit your first post, delete your email address, you could get spammed.
