Hey Doug McGarrett
You're using a different distro so I'm not sure if I can help you, but I would just like everyone to know that I think I've got it. I am now able to print over wifi, and scan with both Xsane and Image Scan over wifi.
If you search for your printer here,
http://download.ebz.epson.net/dsc/search/01/search/ in my experience, if it doesn't say that it requires lsb, then you can install it just fine.
you can see that the driver is shared among several printer models. Go to Print Settings, add printer and if you're printer model is not listed there, choose a model that uses the same driver as YOUR printer, and install it.
Same technique for the scanner driver.
Thanks!
