Im running OSX 10.13.x. Using a standard user account (not admin).

If i have a printer window open, i keep getting a popup that asks for administrators privileges to "Printtool is trying to modify the printer settings" (see attached screenshot).

If i close this popup i can still print fine, but it keeps popping up every minute or so until i close the print window.

Any ideas why this is happening and what i can do to stop it ?

The screenshot in question is for an HP laser jet printer, but i get the same issue for a range of different printers, so believe its something to do with OSX rather than the printer/s.

Try adding your user to the Print Administrators group in terminal:

sudo dseditgroup -o edit -n /Local/Default -a <username> -t group _lpadmin

  • Is there anyway this can be done via GUI ? Also what additional tasks can a Print Admin do that a standard use can not ? – sam Nov 15 '19 at 10:33
  • I don't think so; it's not too scary, just open terminal, enter that command and then the admin user password. As for the other question, it just allows you to manage printers, queues etc. Why you can't do it now without continual nagging, I'm not sure, but this should fix the issue you have :) – FiddleDeDee Nov 16 '19 at 8:01
