Patent ID: 8599414

Claim:
A printing system comprising: a print conversion server configured to supply print data; an image forming apparatus configured to execute printing based on the print data; and a portable device, wherein the portable device comprises: a microprocessor coupled to a memory, wherein the microprocessor is configured to control: an acquisition unit configured to acquire device information from the image forming apparatus to print the print data supplied from the print conversion server by the image forming apparatus; and a requesting unit configured to request the print conversion server to temporarily register the device information acquired by the acquisition unit; wherein, the print conversion server comprises: a microprocessor coupled to a memory, wherein the microprocessor is configured to control: a reception unit configured to receive the request of temporarily registering the device information of the image forming apparatus from the requesting unit; and a registration unit configured to temporarily register the device information received by the reception unit; wherein, the microprocessor of the portable device is further configured to control: a transmission unit configured to transmit, to the print conversion server, information indicating use of the print conversion server at the image forming apparatus corresponding to the temporarily registered device information; and a transmission control unit configured to control the transmission unit not to transmit the information in response to disconnection of communication with the image forming apparatus; and wherein, the microprocessor of the print conversion server is further configured to control: a supply unit configured to supply, if the information transmitted from the transmission unit is received within a predetermined period of time, the print data to the image forming apparatus corresponding to the device information registered by the registration unit in response to an acquisition request of the print data; and a control unit configured to control, when the information transmitted from the transmission unit is not received within the predetermined period of time, the supply unit not to supply the print data to the image forming apparatus corresponding to the device information registered by the registration unit, wherein the image forming apparatus comprises: a microprocessor coupled to a memory, wherein the microprocessor is configured to control; a detection unit configured to detect the disconnection of communication with the portable device; and a requesting unit configured to request, when the detection unit detects the disconnection of the communication with the portable device, the print conversion server to delete the device information corresponding to the image forming apparatus registered by the registration unit.
