Epson R260 and Newer Printers, Drivers are available
 

http://avasys.jp/ The site is in Japanese, at top right hand corner click on 'English'

Has a rpm driver for Fedora for the newer Epson printers that cups doesn't have yet.
You have to install the RPM into cups. and the location of download for your selected printer is the instruction file, be sure to download.
I have a newer Epson Stylus Photo R260 I need to setup , but instruction are confusing.
If someone should succeed please leave feedback.
