WHY, WHY, WHY!!!!

I am trying to set this up for a HP LJ4100, iPrint is installed on NW65
SP2, I have tried every username/password that I can think of?

It appears to be the iPrint client popping this up.

How do I beat this? This should be really simple.

I applied the iPrint NW Post Consolidated SP 11c before trying this.

Thanks.
