I'm trying to troubleshoot an iPrint issue with iPrint client 5.04 and OS X 10.7.3. When I invoke the iprntcmd -t, I receive the following error. The printer is online and available but I am not getting prompted for the novell credentials. Does anybody have a starting point for beginning to troubleshoot this? Have tried uninstalling/reinstalling the client as well as the queue, numerous times. the command works fine on 10.6 and the print job prints without issue. So there is something within Lion that is causing this to fail.
