The driver link you have provided will work. But we have found that if the previous driver is installed on the Mac, the user selects this older driver PPD when adding the printer instead of the new driver PPD because it has UFR in the name, which the new v10.2 driver does not.
So as mentioned this new version UFR2 v10.2.1 includes an uninstaller to remove the old driver and PPDs, thus reducing the chance of the user making a mistake when adding the printer. The next issue is then getting them to select the correct protocol.
I expect that Canon USA will update their site over the weekend to provide this latest version of the driver. Canon Oz gets its drivers direct from Canon INC so that's why we are a little bit earlier with some updates.
