Occasionally users are prompted for their username & password when
attempting to print to an iPrint printer. Secure iPrint is NOT enabled on
any of the users installed printers. If the user cancels the prompt the
document fails. If they try entering their credentials they are not
accepted an the window just pops back up. Generally a complete shutdown/
restart takes care of the issue. All of our users are running WinXP. We
have the 4.26 iPrint client installed. Is anyone else experiencing this?
