Printing broken in Fedora 43 (bazzite-kinoite 43 to be precise)

I am running bazzite-kinoite. Since upgrading from 42.20251019 to the latest 43.x release breaks printing with my Canon TS5300 series Printer (connected via network/wifi). When trying to print anything I get “The printer doesn’t answer”. Some “debugging” information I was able to collect:

Bazzite 43.20251029.0 (Kinoite)
Kernel 6.17.5-ba07.fc43.x86_64

systemctl status cups.service - shows service running

Latest cups.service log when trying to print a test-page with sudo journalctl -u cups.service -b

The print-job gets stuck in the printing queue. When deleting the job the printers status shows “printer ready - gstoraster filter failed”.

When trying to remove the printer and re-adding it I get Unable to connect to 054732000000.local:631: A TLS fatal alert has been received.

When rebasing to bazzite 42.20251019 printing works again.

I am aware this might be a bazzite issue but I suspect it lies with F43 hence me asking here.

I would be grateful if someone could point me how to collect more useful debugging information.

One thing to try is twice-restarting cups.service, after an upgrade. That has been known on occasion to “knock loose” printing functionality when all else failed, for not-entirely-understood (at least by me) reasons.

IOW, after upgrading, literally just…

sudo systemctl restart cups.service
sudo systemctl restart cups.service

(Maybe wait a second or two between them.)

¯\_(ツ)_/¯ Can’t hurt to try.

Thank you for your suggestion. Unfortunately it didn’t help. Apparently CUPS is on the same version in F42 and F43, which confuses me.

Do you have any further ideas on how to collect debugging information?

Bumbeling around KDEs Printing dialog and trying every button and combination in true adventure-game-fashion I fixed the problem.
Before I wasnt able to even add the printer using DNS-SD or IPP with all driver configurations.

After activating “Setup printing server” (top right on the screenshot / Allow setup via network (loose translation, don’t know if those things are actually named this way in english KDE) the printer appeared and I am able to print now.
