We just moved our users from AD Group Policy to Zenworks Group Policy.
We have a user package for GP, and a workstation package for iPrint. I
noticed that a few users are now unable to print via iPrint.

If I log in with my admin account, I am able to successfully print. But
as a regular user (even as a local administrator) the print job will
just hang. Does anyone have any idea how I can fix this?
