should solve that problem. Usually I use Arch Linux so the database for cups is always up to date.
I dont know what Distro you use .. Ubuntu is sudo apt-get install cups && apt-get update...
Best chart for most distro package managers in terminal commands is Pacman Rosetta
Ubuntu also has a bugs webpage for current system printer bugs
PS would highly reccommend backing up system. Cups can hang and cause issues.
