I am a

from the dark side (Macintosh G4 running YellowDog Linux 3.0.1)
My printer is an Epson C43UX.
YellowDog doesn't manage to communicate with it, and the latest model in the printers list is the C42UX. I tried selecting that but still nothing happens when I try test printing.
Any clues for someone who is so new he will need idiot-proof instructions!
Cheers
