Great! You'll appreciate the Linux work about this I think. But this is
GPLed :( The best would be to rewrite it.

I've already tried to understand there work and think about a common project,
but without the hardware...

You'll certainly find such info at the Linux parport project's home page
(see below)

man ppbus on -current

Here are few urls relating to parallel port:

http://www.lvr.com/parport.htm
http://www.lpt.com/pti.htm

There's a Linux project for the HP OfficeJet devices, see the following links:
