Photographer I work for has another Epson (Don't know the types: 2 A3 printers). They both were 'plug and print'....
What was so hard to get the printer to work in the first place?
How is your color management set up? Any chance you're letting both printer and software determine colors (or neither)?
Did a yahoo on 'Gutenprint' and came across a FaQ:

"Q: I selected the right printer and the quality is lousy
A: Try selecting a different resolution or quality setting. Especially lower resolutions have a problem putting enough ink on paper. Also, use Photo mode. If you find settings that do not work at all (you get garbage or no output, but other settings work), report these as bugs. High resolutions should produce a similar (but smoother) result than medium resolutions. Resolutions under a certain printer dependent figure are seen as draft-only - for example lower than 360 DPI on Epsons with standard paper or lower than 300 DPI on HP.
Also make sure that you have the right kind of paper selected. Selecting plain paper when you're printing on high quality photo paper is certain to result in a light, grainy image. Selecting photo paper when you're printing on plain paper will result in a dark, muddy image that bleeds through the paper. There are differences between different kinds of paper; you may need to tweak the density and color settings slightly.
In addition, certain printers don't work well on certain kinds of paper. Epson printers work well on Epson papers, but don't work well on many third party papers (particularly the high quality photo papers made by other vendors). This isn't a conspiracy to lock you into their paper, it's because they've formulated the paper and ink to work well together."
Sounds like not too much color management is going on?
