Look for "io.dll" in google, it is a free 'dll' file from which you can call routines
to access the Parallel Port. With some tricky programming it works in all versions
of Windows.
I have just purchased PureBasic (59 Euros) which works in windows, creates full 32 bit
applications, has a wysiwyg interface generator so you can create nice standard
 'Windows' in minutes, and this connects to the Parallel Port via "io.dll" easily.
I am a novice programmer, only learning enough to get done what I need, and I
created a simple application that drove my P.Port interface in the first couple of days.
