Patent number: 8269999Abstract: The present invention can provide an efficient cancellation of a restriction on a stamp print process without the need for the user to request the manager for a temporary cancellation of the restriction on the stamp print process by phone or orally. The information processing apparatus makes a request for a temporary cancellation of the stamp print process specified in the first policy, and thereby acquires a second policy created outside based on the request. Then, the information processing apparatus temporarily cancels the stamp print process specified in the first policy, based on the second policy.Type: GrantFiled: May 27, 2009Date of Patent: September 18, 2012Assignee: Canon Kabushiki KaishaInventor: Tomohisa Hasegawa
