lanig:
Thanks for the answers.
The Canon installation script does an "apt update" and installs what is necessary. I suppose that all the cups packages are installed. Same answer for the firmware.
I have tried to change the driver to LPB 112 but same result.
If I try to clean the printer I got the message
--- Code: ---Unsupported document-format "application/vnd.cups-command".
--- End code ---
--- Code: --- journalctl -b | grep cups

Could it be an app armor problem ?
eriefisher:
Do you have libcups-filters installed? Should be a t64 version now.
lanig:
I think so :
--- Code: ---dpkg -l |grep cups |grep filter
ii cups-filters 1.28.17-3.1+b1 amd64 OpenPrinting CUPS Filters - Main Package
ii cups-filters-core-drivers 1.28.17-3.1+b1 amd64 OpenPrinting CUPS Filters - Driverless printing
ii libcupsfilters1t64:amd64 1.28.17-3.1+b1 amd64 OpenPrinting CUPS Filters - Shared library
--- End code ---
eriefisher:
I'm not sure what to add at this point. Possibly a firewall issue but you say the printer is detected automatically so this may not be the case.
hendrikL:
If it works as a driverless printer, then there is no need to install extra printing software.
What you can try is to download our latest, in this case kde, testimage, and try to print a testfile. If it's working, then something is broken or miss configured on your system.
