Cannot print on Windows network

Tue Apr 24 02:02:57 PDT 2007

I run cups 1.2.8 on Ubuntu Feisty Fawn. At work i try to connect to a Oce printer over the network, but i can't get it to work. According to my company the printer is located thorugh an url that looks like this: http://po.myorganisation.com/printers/PrinterName/.printer

In Cups i connect using the ipp protocol, and fill in the url.

I can't get it to print though.

When i want to that printer on Windows i need to fill in a username and password. Where can i do that in Cups?

This is what my error_log says:

E [24/Apr/2007:10:57:28 +0200] CUPS-Add-Modify-Printer: Unauthorized

E [24/Apr/2007:10:57:59 +0200] PID 12007 (/usr/lib/cups/backend/http) stopped with status 2!

Any ideas on how to solve this?
