Printing Setup

I'm trying to set up an Epson 880 connected locally via USB to a computer running Yellow Dog Linux 2.3 (PPC port of Red Hat), and have had absolulty no success. It can see the printer on the bus when I type:

more /proc/bus/usb/devices

but beyond that, I can't find any way to designate it as the system's printer. Help, I'm a noob!

Thanks!
