Recently every time I try to use my printer to scan a document I get repeated pop-ups saying printtool is trying to modify my printer settings and asking for the name and password of a "print administrator". I can't find anything about printtool on my mac and have never had a print administrator let alone a password for one. Hitting cancel gets rid of the pop-up but I have to do it multiple times per scan and it's annoying. I think it relates to the latest operating system update. Can anyone help me get rid of this annoyance?
