|Epson ET-2750 on my LAN.|
Epson has released printer drivers for Linux, but the drivers are not made for Arch Linux. I downloaded the drivers, and found the relevant .pdo files, but the USB install did not work as expected in CUPS.
On the tiny printer screen I saw a wifi option, entered the LAN password. Then I could visit the printer on a local tcp/ip address. From the web interface installing the printer was easy.
So don't mess with drivers, just use the wifi options.
