gnome-cups-manager IPP username/pass authentication?

Hi there,

I'm trying to install a network printer at my school to my computer,
using gnome-cups-manager. The only protocol supported is IPP, and my
network username/password is required to connect.  How can I give it my
u/p through gnome-cups-manager?

I was thinking perhaps add a username:pass@ to the beginning of the HTTP
URL, but had no luck with this.

Any help is greatly appreciated.
