I don't have a parallel port on my laptop and I gave away my P16PRO40 so I'm not in a very good position to help you. Sorry.
The WinPic800 software looks very nice and supports a ton of chips but it doesn't list the P16PRO40 hardware specifically. Looks like a couple hardware listings are identical though, including VPP1 and VPP2 selections. Perhaps someone else on the Forum could help you setup the P16PRO40 with it?
