Comment 7 for bug 1814513

OK.

I'll try to download this driver and test installing it in a Cubic chroot environment.
Perhaps there is an error that I can spot. (Since I do not have your printer, I wont be able to test it beyond that). I will also be looking to see if see if the driver installation needs to start a service inside chroot, since you can not start services inside a chroot.

In the mean time, did you try posting your issue on a Cannon forum or help site? You don't need to mention the part about using a chroot environment to create a customized ISO. You can just mention the errors you see while trying to print. Someone else may have run into a similar issue on their Linux environment, and may have a suggestion. Perhaps some other packages are required but the *.deb file from Cannon does not explicitly list those packages as required? (I ask this because the message "Unable to retry job using a supported raster format" implies that some other libraries for supported raster formats may be needed?).

Also, take a look at this:
https://github.com/apple/cups/issues/4253

They suggest using "cupsctl --debug-logging" to get error information.

Th GitHub post above also says, "this is a misconfiguration on your server. You cannot require encryption for Send-Document but not for Create-Job. Whoever maintains your server needs to fix the policy definition to require authentication for Create-Job as well."

If this refers to the cups "server" on your local machine, perhaps it needs to be configured in a different way?
