Just had an issue where I couldn’t set up my printer (connected on the network) on my Ubuntu machine because I didn’t have the drivers. The automatic printer set up would keep crashing half way through.
This post from askubuntu.com hits this issue right on the head: http://askubuntu.com/questions/333534/installing-epson-wf-3520
I thought I’d leave a post here, just so I know where to find it again in case I forget.
