Parallel Printer Problem

[Ben Timby]

My first thought is to check your BIOS, and try enabling/disabling any 
"auto config" features associated with this port. In my experience, ppc0 
*just works*. However, I did a google groups search, and I found some 
threads describing your problem, and providing solutions along these lines.

Good luck!
