The issue is in GTK. I don't think this has anything to do with the CPDB/CUPS changes recently; that's just a coincidence. This issue was introduced in GTK 4.16.1 and the fix hasn't made it into a new GTK release yet, having only been made a few days ago, but perhaps the GTK maintainers can consider cherry-picking if there will be a delay.
I can confirm that merge request 7880, which fixes issue 7109 upstream, solves the issue for me and allows printing again.
