We re-imaged all our staff computers over the summer and added the iPrint printers back. Now some of the printers are getting a Printer authorization window asking to log in. We do not have the secure printing setup so I don't know why this is popping up. It is also not happening to all printers. We updated our servers to 6.5 SP7 over the summer but have not put the new iPrint patch out yet. The iPrint client is version 4.32.
