I think its more than just a Canon drivers aren't supported in Fedora problem. I get no usb listed in "lpinfo -l -v" --with or without Canon drivers, and no local printers listed in system-config-printer or http://localhost:631/
, unless its the non-working "cnijusb:/dev/usblp0". Whenever I try "cnijusb:/dev/usblp0" I get "Unable to open USB port device file: Permission denied".
I hope posting here after the bug report was closed isn't a no-no.
Edit: With the latest Rawhide update, now "cnijusb:/dev/usblp0" isn't viewable with "lpinfo -l -v" and isn't listed as an option with system-config-printer.
