The electronic apparatus may include a communicator comprising communication circuitry, a microphone configured to receive a user voice input and a processor configured to control the communication circuitry to select the external device as a target device for the wireless p2p connection in response to the voice data received from the external device in a process of probing for the wireless p2p connection being consistent with voice data input through the microphone.

Electronic device and control method thereof

An electronic device including: a processor configured to control the electronic device while the electronic device is turned-on and turn-off the electronic device in response to a turn-off command; a network interface card (NIC) configured to periodically exchange a keep awake message with an external server through a repeater while the processor is turned-off; and a power supply configured to supply power to the NIC while the electronic device is turned-off.

Remotely controllable electronic device, network system for controlling the electronic device and remote control method thereof

An electronic apparatus for supporting wireless peer to peer (P2P) communication with an external apparatus is provided, that includes a communicator configured to transmit and receive a signal for performing discovery and group formation, and a controller configured to transmit a first preferred channel list including a channel number indicating at least one channel pre-established among a plurality of channels available as an operating channel, to the external apparatus, to select one channel number from at least one channel number included in a second preferred channel list and the channel number included in the first preferred channel list in response to the second preferred channel list being received from the external apparatus as an operating channel with the external apparatus.

Display apparatus and control method thereof

A method and apparatus for transceiving a message is provided. The method includes: listening for a probe request packet transmitted from another device through a predetermined channel; and, in response to receiving the probe request packet transmitted from the another device, transmitting a probe response packet, and at least one of the probe request packet and the probe response packet includes a user message.

Method for transceiving message, data transceiving apparatus, and non-transitory recording medium

An electronic apparatus includes a job processor to perform a job of the image forming apparatus, a storage unit to store apparatus use information on a user of the image forming apparatus and job performance of the job processor, a determination unit to determine whether the user is changed or not, and a controller to delete the apparatus use information on a previous user if it is determined that the user is changed.

Image forming apparatus and method of managing information thereof

Disclosed is a communication apparatus including: a first communicator configured to connect with an external device by a first communication mode; a second communicator configured to connect with the external device by a second communication mode different from the first communication mode; and a controller configured to control the first communicator to connect with the external device by the first communication mode, control the first communicator to obtain connection information of the second communication mode from the external device, control the second communicator to be connected to the external device by the second communication mode based on the connection information, and control at least one of the first communicator and the second communicator to transmit data to the external device.

Display apparatus and control method of the same

Image scanning apparatus and method of receiving a new scan job, determining whether the new scan job is a multi-scan job, and when the new scan job is a multi-scan job, individually performing the multi-scan job using the plurality of scan units. Accordingly, in the process of performing a scan job, a user can perform a new scan job without waiting.

Image scanning apparatus and method thereof

An image forming apparatus, including an image forming part which forms an image on a printing medium, a main feeding part which accommodates the printing medium and supplies the printing medium to the image forming part, and a reversing part which transfers the printing medium, on which an image is formed on a first surface thereof in the image forming part, to the main feeding part, wherein the main feeding part includes a feeding roller part which re-feeds the printing medium, having been transferred through the reversing part, to the image forming part.

Image forming apparatus capable of forming a duplex image on one sheet

An image scanning apparatus and method accurately sense a leading edge and a tail edge of a scanned document and determine the leading margin and the tail margin of the document. The image scanning method includes feeding the document to a scanning position through a feeding path according to a command to scan the document; operating a sensor unit disposed on the feeding path according to a location of the document; scanning the document in response to operation of the sensor unit; sensing a leading edge of each document using a document sensing pattern disposed oppositely to the scanning unit; and scanning the document when the leading edge of the document is sensed.

Image scanning apparatus and method

An image forming apparatus capable of resizing an image, and a method of resizing the image of the image forming apparatus. A scanning unit scans a document to generate an image. A storage unit stores a target file size to be applied during storing of the generated image before the document is scanned. An image processor resizes an initial file size of the image generated by the scanning unit so that the initial file size approaches the target file size. A controller stores the image having the resized file size in at least one of an external memory connected to the image forming apparatus and the storage unit installed in the image forming apparatus. As a result, a scanned image can be resized to a size desired by a user and then stored in the external memory before the scanned image is stored.
