Since Windows 7, I have been adding the Everyone group to Windows-hosted printers, and checking every permissions box, as a method to drastically increase reliability and controllability, using other groups only if restrictions were necessary. The inestimable Dave Gottschamer just reported a scenario in which Everyone was there, but didn’t work; he tried Authenticated Users and it worked. This is quite the sea change. Not exactly unexpected, as Microsoft has been slowly denaturing Everyone for quite some time, but now we have a definite diagnostic-and-fix change for printers, including desktop USB printers, which will help!
