I just installed a printer utility which enables me to check ink levels. The deb file came directly from Epson's download page, and Ubuntu handled the installation smoothly. But I can't find the utility! It's not crucial because I can still print. Where does stuff like this vanish to? It's not in the "Show Applications" list. When I ran Windows, the utility would pop up when ink was low, but it could also be called from a desktop icon.
The install file is: epson-printer-utility_1.1.1-1lsb3.2_amd64.deb
Try
ls -la /usr/bin | grep epson
on the terminal and check if there is output.
