Comment 24 for bug 564633

Lars Volker, and anyone else who observes a driver search on the internet when a local driver is available, in your case the problem is not the prioritization of locally installed drivers against drivers available on the Internet, but a problem of the fuzzy matching of the make/model information reported by the printer and the information supplied in the PPD files or drivers. Please report a new bug and report the bug number here. For the new bug report run the following commands in a terminal window and post all output here:

lpinfo -i -v

If the printer is a network printer (Ethernet connector or WLAN) connect it via network and run

/usr/lib/cups/backend/snmp
sudo /usr/lib/cups/backend/dnssd

If the printer has a USB connector, connect it via USB and run

sudo /usr/lib/cups/backend/usb
sudo usb_printerid /dev/usb/lp0
sudo usb_printerid /dev/usb/lp0
lsusb
ls -l /dev/usb/lp* /dev/bus/usb/*/*

Run also

lpinfo -l -m > list

and then attach the file "list". Do not compress it.
