Connect Home Office printers to managed devices

AnnaChu Thank you for the link to this post, we are already using Endpoint Manager and are currently preparing our environment for co-management. Nevertheless with support from MS we have meanwhile experienced some positive results with GPO settings and need to test with wider audience. We've enabled these both policies:

1. Computer Configuration/Policies/Administrative Templates/Printers/Point and Print Restrictions and choose : Do not show warning or elevation prompt.

2. Computer Configuration\Policies\Administrative Templates\System\Driver Installation\Allow non-administrators to install drivers for these devices setup classes

The policy “Allow non-administrators to install drivers for these devices setup classes” allows a limited user (non-admin) to install devices from specific device setup classes and install drivers for the device without requiring elevated permissions. The option “Do not show warning or elevation prompt” prevents driver installation warning messages and elevation prompts on computers.

You could find more details from the articles as below:

I hope that our broader tests will be positive as well as with my test machine.
