Digital BW, The Print

i have an epson 2200 and a PowerMac G4 Dual OS 9.2.2 and OS 10.3.9 / i
can print fine on the OS 9 but printing on the OS 10.3 is grainy by
comparison! i just loaded an epson stylus pro 2.0 RIP and have no idea
how to translate that into good printing on the 2200 / can anyone give
me a direction to go? i just returned to the group (as a lurker) from
an absence while i figured out my new bellsouth DSL extreme service
and want to do some printing but feel overwhelmed!    jwp
