I'm facing similar issues, as our networked Xante printers aren't listed
either. My solution was to simply use the "Generic Postscript" driver,
and that works fine for me. I recommend you to try this as well, unless
Canon provides proper Linux drivers which can be installed (dunno how to
add 'em to CUPS, as I've not yet have to do so).
If your printer is a very new model, perhaps in a future update of CUPS
it will be featured, so I'd keep checking the printer drivers after CUPS
updates...
Cheers!
