My printer Brother DCP-T510W, connected via WiFi, got automatically detected by Ubuntu 18.10, but its functionality was limited (like for example scanning didn't work).
Decided to install manufacturer's dedicated linux driver - that resulted in additional printer entry in Settings/Devices/Printers, but this one is fully functional (the second one).
Tried to delete the first, automagically detected entry, but it comes back right after deletion (whaaa?).
How can I get rid of the first entry then?
Already tried:
- all cups related fixes found in net - didn't help (http://localhost:631/printers/ shows only the second entry though)
- avahi configuration
enable-dbus=nofix - this disabled the first entry, but it resulted in significantly longer printer discovery and other software experiencing some hickups.
