Print driver isolation groups

Are you specifying an FQDN or a short name? FQDN is required. Also, are you setting it in both point and print, and package point and print, depending on if the drivers are package-aware.

For kicks I added to the same policy to the Users side as well and same behavior. Good question. Yes, drivers were previously installed on those test VMs.

Not quite sure what might be going on. I just did my test on another VM, no print drivers at all.

Once the driver is determined to be sufficiently stable, the administrator can move the driver to the shared process. You can configure the Printer Driver Isolation mode for a printer driver from under the All Drivers node, a custom driver filter node, or the Drivers node for a print server.
