Hi,
maybe a developer could look at this low-level API for Windows, which would allow access to the parallel port:
Description (german), scoll down to CrackNT:

API (english)

I'm not a software developer, nor do I use the parallel port interface or this API. I don't know if it is easy to integrate. I hope, maybe it is useful for you.
regards
