Abstract
Abstract An apparatus in a system in which a data source, a server, and the apparatus are connected on a network includes a receiver for receiving a direct command from the data source for requesting direct communication between the data source and the apparatus. The apparatus also includes a judging unit for judging whether a direct command can be accepted when the direct command is received during a data communication with the server, and a controller for interrupting the data communication with the server when it is judged that the direct command can be accepted. The direct command allows a printing/scanning function of a data input/output apparatus connected to the apparatus to be executed without passing through the server.
