I have a new Epson ET-2650 printer, which is connected to a Windows machine via USB. Works fine on Windows 7. I'm trying to print to this printer from a Ubuntu machine via a Samba connection. Unfortunately, the list of Epson printers on Ubuntu doesn't include any of the ET-series printers. (These are the new "ink tank" machines; the printer costs more but the ink is much cheaper).
I've tried setting the make and model to "Generic PostScript Printer Foomatic/Postscript (recommended)". Printing the test page results in printing the Postscript source as text, with the comment "If you can read this, you are using the wrong driver for your printer".
I tried looking on the Epson installer CD-ROM for a PPD file, but didn't find one.
No PPD file for this printer here: http://www.openprinting.org/driver/Postscript-Epson/
Ubuntu 14.04 LTS x64.
