This behaviour is replicated exactly as described above with
Fedora-Workstation-Live-x86_64-24_Beta-1.6.iso, which has cups 2.1.3.

openSUSE-Tumbleweed-GNOME-Live-i686-Current.iso has the same CUPS
version and behaves in a slightly different way (no network printers
are displayed with either "Find Available Printers" or "Add Printer"),
but I'd say the behaviour is again identical to Debian and Fedora.

(I never saw Mike Sweet's responses in cups-devel; maybe due to the
change to Git. Something for me to sort out sometime).

Cheers,

Brian.
