lpr: Unauthorized Message

If users are getting the lpr: Unauthorized message on CUPS servers, look for the following setting in the /etc/cups/printers.conf file...

AuthInfoRequired negotiate

In my case, I found this setting on two Samba print queues. I changed it to match my other Samba queues, like so...

AuthInfoRequired username,password

And restarted cups, which fixed the problem.
