I've got the same problem. After chosing a driver for my printer (hp or hplip), there isn't any printer in the gnome-cups-manager (or cups web interface).
Next a part of my /var/log/cups/error_log file (after try to add my printer) : E [12/Apr/2006:22:52:55 +0200] cupsdLoadAllPrinters: Unable to open /etc/cups/printers.conf - Aucun fichier ou répertoire de ce type E [12/Apr/2006:22:52:55 +0200] cupsdLoadAllClasses: Unable to open /etc/cups/classes.conf - Aucun fichier ou répertoire de ce type E [12/Apr/2006:22:52:55 +0200] LoadAllSubscriptions: Unable to open /etc/cups/subscriptions.conf - Aucun fichier ou répertoire de ce type E [12/Apr/2006:22:53:11 +0200] [cups-driverd] Unable to open driver directory "/usr/lib/cups/driver": No such file or directory E [12/Apr/2006:22:53:34 +0200] CUPS-Add-Printer: Unauthorized E [12/Apr/2006:22:53:34 +0200] copy_model: empty PPD file!
