Printer ports are parallel ports (8 bits travel on 8 wires simultaneously) and you can find a transfer program on the www, but why?
Serial ports are, um, serial ports (bits travel like a line of ducks) and you can find a 115kbps transfer program on the www, but why?

Network cables are also serial, but transfer data at 10Mbps, 100Mbps and now 1Gbps.
- Connect a cable between the two network ports, or connect both computers to a router.
- On your Windows box, set up Netowork Neighborhood's file sharing (instructions in Windows >> Help or on the web).
- On your Linux box, set up SMB (Samba) - instructions are everywhere on Knoppix or Debian-based Linux forum sites.

Why not just burn it all to DVD / CD or USB thumb drive?
