IE7 Protected Mode -Vista - iPrint

So.. I hope someone can point me in the right direction. How does one print from IE7 in Vista using an iPrint printer without;

1. Disabling Protected Mode
2. Running the browser as Administrator (thereby disabling Protected Mode)

Attempting to print in Protected Mode will result in the following error message;

"Document failed to Print" and the status shows "Creation Failed".

I know this has been posted before with no answers. This has been deemed a "show stopper" for Vista/iPrint deployment within our organization.

Also.. to add to the list are the following "missing" components;

1. Ability for the iPrint Client to grab credentials from the Novell Client.

2. Lack of support for driver profiles.

Is a new iPrint client on the way?
