Cannot delete automatically detected printer (after driver install two entries are present in result)

My printer `Brother DCP-T510W`, connected via WiFi, got automatically detected by eOS, but it was shown as `disabled` although it was printing stuff. The scanning however didn't work.
Decided to install manufacturer's dedicated linux driver - that resulted in additional printer entry in eOS's `Settings/Printers` section, this time marked as enabled, and with all functions working.
Tried to delete the disabled entry, but it comes back right after deletion :astonished:
**How can I get rid of the disabled entry then?**
