Mystery printer in firefox under Ubuntu 14.04.5

[Robert Heller]

For some unknown reason a "mystery" printer is showing up in FF's selection of
printers. This printer does NOT show up in 'lpstat -t'. It is not in
/etc/cups/printers.conf. And I know for sure that I uninstalled the (stupid)
deamon that finds new random printers (don't need or want that sort of "user
friendliness"). Is this a Ubuntu issue or a Firefox issue or a Unity/Gnome
issue? I have not seen this on my CentOS machines, ever. It only seems to
happen on the diskless Ubuntu machines I set up using DRBL.
