Abstract: A mobile terminal (communication apparatus) selects a data item that needs to be obtained from an MFP (information processing apparatus) according to a user instruction given via an operation screen. Upon establishment of NFC communication between the mobile terminal and an NFC tag of the MFP as a result of the mobile terminal being brought closer to the NFC tag by the user, the mobile terminal reads, from the NFC tag, connection information for connecting to the MFP by using the Wi-Fi Direct. The mobile terminal connects to the MFP by using the Wi-Fi Direct based on the obtained connection information, and obtains data corresponding to the selected data item from the MFP through the Wi-Fi Direct communication.

Abstract: A printing apparatus which prevents communication from becoming impossible. The printing apparatus has a control unit and a printer unit. At start-up of the control unit, a first communication speed is set as a communication speed for communication between the control unit and the printer unit, and also a predetermined command is transmitted to the printer unit. Whether or not a response to the predetermined command has been received from the printer unit is determined. As a result of the determination, when no response to the predetermined command has been received from the printer unit, a second communication speed different from the first communication speed is set as the communication speed for the communication between the control unit and the printer unit, and also, a reset command is transmitted to the printer unit.

Abstract: A mobile terminal 102, when an MFP 101 is approached, transmits to the MFP 101, using a short-range wireless communication, a scan start instruction and access information. Furthermore, the mobile terminal 102, when job-related information related to a job is received, publicizes accessibly a storage area, and when the job corresponding to the job-related information completes, makes the publicized storage area to be unpublicized. On the other hand, the MFP 101 receives the scan start instruction and the access information, issues the job-related information, notifies, using the short-range wireless communication, the mobile terminal of the job-related information, and stores the image data read from the original in accordance with the start instruction by accessing the publicized storage area.

Abstract: An information processing apparatus (printing server) of one aspect of the present invention generates print data from the print target file attached to the electronic mail received from a mobile terminal via a network, and causes the printer designated in the electronic mail to execute printing based on the print data. Upon receiving such electronic mail, the print server saves the electronic mail address of the transmission source of the electronic mail. In addition, when the installation state of a print driver changes, the print server notifies a mobile terminal corresponding to the saved electronic mail address of information indicating the change by using the saved electronic mail address.

Abstract: An electronic device is provided that is capable of dealing with data loss from a volatile memory that can be caused when power supply from a device power source is disconnected. Even if there is a setting to retain received data in the volatile memory until a printing instruction is given by a user, the electronic device, e.g., an image forming apparatus, prints received data without waiting for the user's printing instruction in a case where a backup battery voltage is less than a predetermined value.
