Axios If usb is hooked up unplug it and try setting up.
Tried that but couldn't add the printer Cup admin said unable to find PPD file for printer, probably because it is a recent printer. Still works on IPP Everywhere tho.
Where would I raise an issue?
Edit: Found the issue page there are already several issues for Canon AIO Printers including cnijfilter2 which has been approved but needs a maintainer. I think this would solve my problem.
