Enable Printer Sharing
Computer Configuration > Policies > Centrify Settings > Mac OS X Settings > Services > Enable Printer Sharing
Allow other people to use printers connected to the local computer.
Enabling this group policy is the same as opening the Sharing system preference and selecting the Printer Sharing option.
On Mac OS X Servers, enabling this policy has no effect.
This policy can take effect dynamically at the next group policy refresh interval without rebooting the computer.
