I have installed my HP Deskjet F4400 All-in-One printer within Debian, Ubuntu and Fedora. Today, I have received the following error (I have posted a screen grab as well):
Filter "/usr/lib/cups/filter/foomatic-rip" for printer "HP-Deskjet-F4400-series" not owned by root
My attempts to follow Ubuntu-based instructions from Ubuntu Forums (e.g. chown root:root for /usr/lib) resulted in my inability to connect wirelessly, change CPU frequency and shutdown via a GUI.
Would anyone here be so kind as to assist me in alleviating my system of its current printing problems?
