We are testing the new Printer Center - Centralized mode for our v9.1 Release stations. We ran into an access problem wherein our Release stations are on a limited access VLAN and when we switch to Centralized, the release station screen was only a blank grey with a Cancel tab that does do anything. I believe there are new ports that need to be opened to the Print Server. Is there a list of new ports? I didn't see anything in the documentation. Thanks.
