Devices: Prevent users from installing printer drivers
For a computer to print to a network printer, the driver for that network printer must be installed on the local computer. The Devices: Prevent users from installing printer drivers policy setting determines who can install a printer driver as part of adding a network printer. When you set the value to Enabled, only Administrators and Power Users can install a printer driver as part of adding a network printer. Setting the value to Disabled allows any user to install a printer driver as part of adding a network printer. This setting prevents unprivileged users from downloading and installing an untrusted printer driver.
This setting has no impact if an administrator has configured a trusted path for downloading drivers. When using trusted paths, the print subsystem attempts to use the trusted path to download the driver. If the trusted path download succeeds, the driver is installed on behalf of any user. If the trusted path download fails, the driver is not installed and the network printer is not added.
Discussion
Although it might be appropriate in some organizations to allow users to install printer drivers on their own workstations, this is not suitable for servers. Installing a printer driver on a server can cause the system to become less stable. Only administrators should have this user right on servers. A malicious user might deliberately try to damage the system by installing inappropriate printer drivers.
It is advisable to set Devices: Prevent users from installing printer drivers to Enabled. Only users in the Administrative, Power User, or Server Operator groups will be able to install printers on servers. If this policy setting is enabled, but the driver for a network printer already exists on the local computer, users can still add the network printer. This policy setting does not affect a user’s ability to add a local printer.
