Canon iP 4300 as default printer with openSuse 12.1

It looks to be impossible to configure my Canon iP 4300 printer as the default printer. The CUPS system always sets my very old HP Officejet, which is not connected to the system now, because it does not work correct with the driver installed by CUPS. >:)
Each printing operation needs a selection of the correct, and only working printer. Otherwise nothing happens!

Did you try removing the HP printer in Yast>Hardware>Printers?

Yes i did it now, and it is ok. Thanks for help.
