Only to the queue added via lpadmin ... everywhere

No autodetected printers appear in system-config-printer or application print dialogs.

$ sudo lpadmin -p testq -v "ipp://Brother%20MFC-L2740DW%20series._ipp._tcp.local" -E -m driverless:"ipp://Brother%20MFC-L2740DW%20series._ipp._tcp.local"
[sudo] password for user: 
lpadmin: Printer drivers are deprecated and will stop working in a future version of CUPS.

$ lp -d testq /etc/nsswitch.conf
request id is testq-12 (1 file(s))

Nothing prints over 5GHz, nor 2.5GHz wifi connections.

Same behaviour as before in both cases - printer lights up but nothing prints.

Thanks,
Gareth
