Setting the policy designates which access policy applies to bulk printer configuration, controlling which printers from PrintersBulkConfiguration are available for users.
* BlocklistRestriction (value 0) uses PrintersBulkBlocklist to restrict access to the specified printers
* AllowlistPrintersOnly (value 1) uses PrintersBulkAllowlist to designate only those printers which are selectable
* AllowAll (value 2) displays all printers
Leaving the policy unset puts AllowAll in use.
