I have an EPSON Stylus C45 inkjet printer and I was looking for a tool in Ubuntu to monitor my printer Ink levels and ended up with a nice tool for the GNOME desktop. It is called Inkblot. Inkblot supports almost all inkjet printers of EPSON and HP and Stylus C45 works perfectly. It can be installed by the following way…
Open a terminal and type
sudo apt-get install inkblot
Add the inkblot to GNOME sessions and it will monitor your printer ink levels in the background on a Panel.
