SUMMARY
Hey guys, the printer manager automatically discovered printers in my network (which is great), but doesn't use the correct driver by default (which is not so great), but the worst thing is that every time I remove the printer (by pressing on "remove printer"), the printer just reappears again, bloating my printer menu with printers I can't use, since they don't work correctly / of printers I don't use.
Even automatically recognized printers should stay removed, as they could easily be re-added when needed and it's just confusing that they reappear and might lead to confusion on what printer to use for an inexperienced user (the badly configured driver is a different story here)

STEPS TO REPRODUCE
1. have a printer in the network that can be discovered 
2. remove it from the printer list
3. wait for half a second

OBSERVED RESULT
the removed printer reappears

EXPECTED RESULT
the removed printer stays removed
