   Ok. so i tried to upgrade gutenprint and to kill cupsd but none of these
   worked :-(
   I had a conversation with a developer of libinklevel and he told me that
   printers go to some "sleep" state when run out of ink. Could this be my
   case? The printer is blinking red and wont print anything... If yes, how
   can i awake my printer to get ink levels?
   fuser and lsof gave me no informations :-(

They do, but they usually won't fail to open in this situation.

Try removing any jobs from your printer queue and rebooting the system
to make sure nothing's trying to open it.
