Windows Network Printing Problems

I have a network that includes a Dell running Windows XP and a cable modem that is split at a Linksys router. The router connects to the Dell and also to my Apple Airport Express. The Dell has an Epson 880 Sylus Color by USB. I am trying print from my iBook which using the Airport connecting and I used the instructions found on the Apple Help on printing to a Windows Network. But each time I try to print I get an error message "the process "rasteroprinter" stopped unexpectedly with status 2". What does it mean and what am I doing wrong?
