The problem is that often the model information which a printer reports back on an auto-detection request (device ID) is not in printer database at it is not known to us. And as it often does not match the exact writing of the human-readable printer name in the printer list, the matching sometimes fails.
In printerdrake which I have developed at Mandriva in the last 6 years, I have implemented a fuzzy matching which succeeds in very many cases (but is also not 100% perfect). If we replace the unmaintained gnome- cups-manager by printerdrake, probably many of these issues will go away.
