I confirm that. Tests, I made, shown that kdeprint don't use ~/.cups/lpotions. I don't know yet where kdeprint store the user configuration, but gnome-cups-manager show the enblem of the user default printer assigned by kdeprint, and do not care about ~/.cups/lpotions.
In the same time as it has been discuted, assigning default printer and properties with g-c-m is saved in ~/.cups/lpotions. -- root privileges needed to set default printer https://launchpad.net/bugs/41304 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
