Abstract: A printing system includes an image forming apparatus that accepts a printing instruction from a mobile terminal, sends an inquiry to a server as to whether a printing reservation corresponding to the accepted printing instruction is managed by the server, and transmits connection information to the mobile terminal if the printing reservation is managed by the server. The image forming apparatus obtains printing data corresponding to the printing instruction from the mobile terminal set in the connected state, executes printing processing using the obtained printing data, and sets communication with the mobile terminal to an unconnected state after execution of the printing processing is complete. If the printing reservation corresponding to the accepted printing instruction is not managed by the server, the printing instruction accepted from the mobile terminal is rejected and the connection information is not transmitted to the mobile terminal.

Abstract: When, in communication using a protocol in which at least two streams are established over a connection, a notification that a new stream will be reserved is made, a process for preventing a non-communication state exceeding a predetermined amount of time is initiated and a frame is sent at least every predetermined amount of time in the case where there is no other stream currently reserved, whereas processing is ended without initiating the stated process in the case where there is already a reserved stream.

Abstract: In the image forming apparatus, accepting a printing instruction from the mobile terminal, inquiring whether the management server manages a printing reservation corresponding to a printing instruction when the printing instruction is accepted, transmitting connection information to the mobile terminal when the printing reservation corresponding to the printing instruction is managed as a result of an inquiry, setting communication with the mobile terminal as a connected state when a connection request from the mobile terminal using the connection information, obtaining printing data corresponding to the printing instruction from the mobile terminal set in the connected state, and executing printing processing using the printing data. Communication with the mobile terminal is set to an unconnected state after execution of the printing processing is complete.
