A specific communication device may send specific identification information for identifying the specific communication device to an external via a communication interface, wherein the external device may display a screen including the specific identification information in a case where the external device receives the specific identification information from the specific communication device; and in a case where a specific condition including that the specific identification information is sent to the external is fulfilled, a state of the display unit may be changed from a first state to a second state, the first state being a state in which the display unit does not display the specific identification information, and the second state being a state in which the display unit displays the specific identification information.

A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.

In a system in which communication between an information processing apparatus and a printing apparatus is possible, the information processing apparatus detects that communication with the printing apparatus has become possible and, in response to detection that such communication has become possible, generates print data based upon data that the information processing apparatus is displaying on a display unit connected to or built in the information processing apparatus, and transfers the generated print data to the printing apparatus. The printing apparatus prints the data received from the information processing apparatus.

An information processing apparatus which makes it possible to make communication settings with ease. A mobile terminal as the information processing apparatus includes a Bluetooth controller that causes a Bluetooth communication section to receive a packet, a CPU that generates a device list, based on the packet, a display section that displays the device list. The CPU selects a device from the device list based on a received radio field intensity of the packet or selects a device from the device list based on a selection operation by a user. The mobile terminal further includes a wireless LAN controller that cause a wireless LAN communication section to transmit data to the selected device.

A portable terminal includes a user interface, a memory, a network interface, and a controller, and performs operations including: performing a first acquiring processing of acquiring the content data, which is identified by the data identification information, and the operation identification information; performing, a second acquiring processing of acquiring operation information representing operations, which is able to be performed by the first device; performing, a first determining processing of determining whether the output operation, which is identified by the operation identification information, is represented by the operation information, and transmitting, in the output instructing processing in a case where it is determined that the output operation is represented by the operation information, a first output instructing information to the first device via the network interface, wherein the first output instructing information is output instructing information for outputting the content data by the output operation.

A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.

A non-transitory computer-readable recording medium storing a first instruction-set of computer-readable instructions for a terminal device. The first instruction-set causes, when executed by the controller, the mobile terminal to receive a user operation to designate a designated second instruction-set through the input interface, and determine whether the memory stores designated device information including an operation ID identifying a designatable operation. When the designated device information is not stored in a memory, the mobile terminal searches for an image processing device capable of executing the designatable operation, receives a user operation to designate the designated device, stores designated device information in the memory, starts the designated program, obtains the operation ID of the designatable operation from the designated program, and transmits first instruction information to the designated device. The first instruction information is information causing the image processing device to execute the designatable operation identified by the operation ID as obtained.

An image forming apparatus includes a communication portion arranged inside a cover covering an image forming portion in the main body of the apparatus and including an antenna surface for use in establishing near field communication. The cover includes a stacking portion in its upper section. The stacking portion is configured to receive a recording medium with an image thereon, the recording medium being discharged outside the main body of the apparatus. The antenna surface faces a region of the upper section of the cover downstream in a direction of discharging the recording medium. The antenna surface at least partially faces a region of the upper section of the cover outside the stacking portion in a direction perpendicular to the direction of discharging the recording medium. The communication portion is capable of communicating with another communication portion using near field communication.

A method for controlling image-forming devices includes acquiring currently-available wireless networks, including detecting the currently-available wireless networks and acquiring broadcast information transmitted by each wireless access point by a wireless communication module in an electronic terminal; searching image-forming devices through the currently-available wireless networks and establishing a list of the image-forming devices; according to the list of the image-forming devices, selecting a target image-forming device; and connecting to a wireless network corresponding to the target image-forming device and establishing a communication with the target image-forming device, thereby controlling the target image-forming device to execute an image-forming task.

A printing device has a print unit for printing on roll paper; a wireless communication unit for communicating wirelessly with a paired control device; and a controller for receiving print data by wireless communication from the control device, and controlling the print unit based on the received print data. When changing from a pairing-disabled mode to a pairing-enabled mode, the controller controls the print unit to print pairing-related information on roll paper, does not process pairing in the pairing-disabled mode, and processes pairing when a pairing request is received in the pairing-enabled mode.
