You might or might not, by default, be receiving a notification (by way of a pop-up message) when your print job has been completed. If you do and it’s an irritant, or if you don’t and you need it, use this Registry edit.
Navigate to:
HLM\SYSTEM\CurrentControlSet\Control\Print\Providers
Here, create or modify a (the) DWORD value called NetPopup. Set its value to 1 to enable the pop-up notifications, and to 0 to disable them. Restart the Print Spooler service for the change to take effect. You might need to restart Windows if that doesn’t work.
