Every other attempt to print fails with a varying message depending on the printing app (eg. on libreoffice write, "Cannot start printer"). Waiting a few minutes and retrying prints successfully. Looking at cups.service journal messages while attempting to print, it looks like the second printing attempt crashes cupsd cupsd[<pid>]: free(): invalid pointer systemd[1]: cups.service: Main process exited, code=dumped, status=6/ABRT systemd[1]: cups.service: Failed with result core-dump The service then proceeds to restart after a few seconds, and trying to print again succeeds. Trying to print once more thereafter triggers the issue again. I could not find a trace of the coredump, and cuspd's error_log shows nothing happening around the crash (it does show some "org.freedesktop.ColorManager.AlreadyExists" error messages on restart, but I figured this would be normal, I can see the same message on other machines that have no printing issues). I would expect this kind of event to trigger an apport report, but there is no apport popup when it happens. Maybe because it's not a user process, not sure (this is not my usual setup, I've not been using Ubuntu for years). This is a pretty standard (and recent) ubuntu install, with not much customized; in particular no apport custom config was made, and nothing was configured on cups side or ubuntu print settings, everything is set up as it was autodetected on install. The same printer works flawlessly on a different computer using Arch and cups 2.3.3 as well (albeit without any ubuntu patches, obviously).
