Well I looked here
http://www.torque.net/linux-pp.html
and on Sourceforge and couldn't find anything.
Why not buy two Network Cards (less than $10 each), and Crossover Network Cable ($10?) and build a little Ethernet LAN.
The speeds you'll get for file transfer and the like are FAR FAR higher than you'll get with a parallel port connection.
Just my $0.02
Cheers
