Can't print wirelessly via Airport Express

[grimmy]

Help! I have an Epson T10 printer and configured it to the Airport Express (this is the old old version, probably the first) and I can't print wirelessly using a Macbook Core Duo 2.0.

The printer is detected in Bonjour, drivers say it's installed properly. However, when I print, nothing comes up, it just stays in the printer cue. Is this printer non-mac friendly?

Ironically, wireless printing with the same Printer and Airport Express works fine using a windows laptop or desktop.
