Why assume that because you are having a problem doing so, that it is the same across the board for everyone?
I have never had any problems doing so, even the first time I ever used openSUSE.
Perhaps a better way to start a thread, and get help, would be to simply ask something like: “Can anyone help me install a Canon printer in openSUSE?”
(BTW: I have several Canon printers, all with Linux drivers provided by Canon, and all working as I expect them to. But, from other’s reports, that sounds like a rarity? So, I do not know what I am doing wrong to get them to work right.)
