Dear Maintainer, I recently upgraded a Debian 12 system to Debian 13, and immediatly after doing so, could only print from KDE apps. All GTK apps no longer show any configured printers, and those that do (Firefox) are unable to print. CLI tools can also print and list printers just fine. It's only GTK applications that suffer this issue. I found similar reports from many years ago, but none of those solutions helped or were already applied. This affects all user accounts on the machine.
