Mine post is simply one of empathy, since I seem to be having the same problem with Knoppix 3.7. I see lots of USB options when I attempt to install my printer, but the LPT port does not seems to be recognized. Glad I'm not alone.

For what its worth, Knoppix 3.4 and 3.6 are fine on my machine, and both recognize my printer and LPT port just fine.

Mine is not an IBM machine. I've got an Asus P2B motherboard. I've just flash updated the bios, but that did not solve the problem unfortunately.

In posting this, at least it will rise back to the top of the list, where I hope that someone will see/respond to our call for help!
