"This policy setting restricts the servers that a client can connect to for point and print. The policy setting applies only to non Print Administrators clients, and only to machines that are members of a domain.

When the policy setting is enabled, the client can be restricted to only point and print to a server within its own forest, and/or to a list of explicitly trusted servers.

When the policy setting is not-configured, it defaults to allowing point and print only within the client's forest.

When the policy setting is disabled, client machines can point and print to any server."
