Devices: Prevent users from installing printer drivers when connecting to shared printers For a computer to print to a shared printer, the driver for that shared printer must be installed on the local computer. This security setting determines who is allowed to install a printer driver as part of connecting to a shared printer. If this setting is enabled, only Administrators can install a printer driver as part of connecting to a shared printer. If this setting is disabled, any user can install a printer driver as part of connecting to a shared printer. Default on servers: Enabled. Default on workstations: Disabled Notes This setting does not affect the ability to add a local printer. This setting does not affect Administrators. Counter Measure: Enable the Devices: Prevent users from installing printer drivers setting. Potential Impact: Only users with Administrative, Power User, or Server Operator privileges will be able to install printers on the 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. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Devices: Prevent users from installing printer drivers (2) REG: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Providers\LanMan Print Services\Servers!AddPrinterDrivers
