Hello,
The normal user haven't the permission to use the Epson status monitor (to see
ink level for exemple).
I have the following error message (in French) when I try to launch it (in
config menu and in Gimp):
"Pas de droit d'accès aux fichiers /dev...
Remédiez à ceci. Consulter la documentation si nécéssaire"
I think it could ask for root password.
For info, I have an Epson Stylus Color 480SXU (USB).
Thanks to take a look to it,
Florent
