GNOME Bugzilla – Bug 786765
No Printers showing up as configured
Last modified: 2019-11-08 10:55:11 UTC
The Printers panel shows no printers configured, GTK+'s "Print" panel shows 2 printers, I only ever set up a single printer.
gnome-control-center -v doesn't show any useful information.

Printers Settings panel
For the record: It seems that cupsGetDests doesn't work as expected in most recent Cups available. See https://bugzilla.redhat.com/show_bug.cgi?id=1484916
The Gtk+ dialog uses the httpConnectEncrypt API to query for the printers list in a http request-like fashion.
Could you downgrade CUPS to 2.2.3-6? (available in Koji only) If the printers show up then then this is not gnome bug.

Yes, that fixes it. But is it a bug in CUPS, or does something need to change in the Printers panel?
Since neither the function cupsGetDests() nor cupsGetDests2() were deprecated and the change happened between stable releases I think that it is a bug in CUPS. We can wait until it is resolved in Fedora bugzilla to be sure.
This has been fixed in CUPS some time ago.
