I use a DLL that was written in CVI to control the parallel port. CVI
drivers for Inport and out port will work under windows NT. This is not a
fast solution but it does work.
Also a long time ago (In a galaxy far far away) there was a canned Import
and outport DLL that worked with LabVIEW under Windows NT on Nationals
Instruments web site. If you cannot find it, I could email you the dll I
wrote but it is designed to work with EPP printer ports.
