E [20/Dec/2016:10:07:03 +0000] [CGI] File \"/usr/lib/cups/backend/driverless\" has insecure permissions (0100755/uid=1000/gid=1000).
Fixed with 'chown root.root /usr/lib/cups/backend/driverless'.
'lpinfo -v' now gives the same consistent output (50/50) as 'driverless'.
For good measure I tested with the backends on the client re-enabled
too.
The CUPS web interface has
HP ENVY 4500 series (driverless) (HP ENVY 4500 series)
in discovered printers and offers
HP ENVY 4500 series. driverless. cups-filters 1.13.1 (en)
as the model.
system-config-printer puts
HP ENVY 4500 (envy4500.local)
under "Network Printer and goes on to install a queue with an everywhere
PPD after searching for drivers.
Cheers,
