Hi Stephen:

I am running Ubuntu 14.04

I downloaded the *.deb file from the Epson web site:

epson-inkjet-printer-escpr_1.4.5-1lsb3.2_i386.deb

Getting the right LSB package installed can be a pain. If you're not using paper larger than Letter, the standard CUPS ESC/P-R driver should drive this printer fairly well.

I've had the larger (size of a small tank, to be honest) WF-7520 for years, and it's been great. Duplex ADF scanning, SANE support over the network, scan to SD card (which appears as a samba share on the network) ... it just works.

cheers,
Stewart
