I just read a very similar thread on this subject with OpenSuse 12. The problem was resolved by switching to the proprietary Epson drivers. I've installed every driver that I could find for my Epson NX420, and I can't be sure which drivers I'm actually using anymore. I've installed Gutenprint with Yast, and I've downloaded a number of rpms from the Epson website and installed with zypper. The key rpm, I believe, is epson-inkjet-printer-nx420-1.0.0-1lsb3.2.i486.rpm.
I have accessed the Cups interface, or whatever you call it, a number of times, edited my printer, and manually selected the ppd file. Here is the one that I have selected.
It didn't fix anything. Even after a reboot.
There's a boat load of ppd and ppd.gz files in here
How do I know that I am using the right drivers? How do I get the colors on my printer to line up?
