"New printer installed" notification spam

Today I decided to print something, so I went into the printer settings. There it immediately detected my HP wireless printer. Nice! The problem I now have is that I receive multiple "New printer installed" notifications. I removed the printer in the hopes it would stop, but no, I continue to get these together with it being installed. How can I keep the printer in the settings witout it being reinstalled all the time?

Solution:

Turns out: After a reboot it stops. So, yay?
