An image forming apparatus includes a communication interface capable of communication over a plurality of frequency bands and a controller configured to determine whether the content of communication of the communication interface satisfies a predetermined condition. The controller is configured to execute control for switching the frequency band of communication via the communication interface to another frequency band over the frequency bands when the content of communication of the communication interface satisfies a predetermined condition.

A non-transitory computer readable storage medium storing computer readable instructions that are executable by a computer in an information processing apparatus having a communication interface, through which the information processing apparatus is connected with a printer, is provided. The information processing apparatus has a first channel and a second channel configured to cause the printer to print an image based on image data. The computer readable instructions, when executed by the computer, cause the computer to conduct a first printing control to cause the printer to print the image through the first channel, determine whether image printing to print the image by the printer under the first printing control failed, based on a determination that the image printing under the first printing control failed, conduct a second printing control to cause the printer to retry the image printing based on the image data through the second channel.

In a case where an image forming apparatus operates as a master station determining a communication channel used in wireless communication, the image forming apparatus transmits a second trigger frame that includes information indicating inexecution of carrier sensing and complies with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, to a slave station apparatus connected to the master station.

An image processing system includes a portable terminal and an image processing device that wirelessly communicates with the portable terminal. The portable terminal includes a first CPU that sends a connection request to the image processing device to request to establish a connection with the image processing device and that sends an execution start command to enable the image processing device to execute a job when the connection with the image processing device is established. The image processing device includes a wireless communication interface that establishes the connection with the portable terminal in response to the connection request from the portable terminal and a second CPU that receives the execution start command from the portable terminal, executes the job based on the execution start command in order of receipt, and terminates the connection with the portable terminal after the execution start command is received.

A control method including switching, in accordance with receipt of a print instruction, from a first state to a second state in which communication with an external apparatus based on a second communication method is possible and communication with the Internet based on a first communication method is not performed, while connection to the Internet based on the first communication method and connection to the external apparatus based on the second communication method are established and maintained in parallel.

A disclosed example is a server residing on a first network. The server has an observer. The observer receives observational data from a media processing device residing on a second network via a first persistent connection between the media processing device and the server. The observer provides, via the first persistent connection, a configuration file to the media processing device that defines a type of the observational data to be collected by the media processing device. The observer is prevented from communicating an operational instruction to the media processing device. The operational instruction is to control media processing hardware of the media processing device.

An information processing apparatus includes plural communication units, a determination unit, and a controller. The communication units are configured to conduct a wireless communication at different communication speeds. The determination unit is configured to determine a communication unit having a faster communication speed in order to transmit or receive an encrypted communication object. The controller is configured to perform a control to start a communication by the communication unit determined by the determination unit.

A control method of an information processing device that is capable of performing communication by Wi-Fi? and communication by Bluetooth? includes accepting a predetermined instruction based on a user operation to the information processing device, executing, after the predetermined instruction is accepted, displaying processing that displays a predetermined screen that is a screen for allowing the information processing device to communicate with a communication device by Wi-Fi? based on a fact that the information processing device is not able to perform communication with the communication device by Wi-Fi?, and executing, after the predetermined instruction is accepted, communication processing that communicates, with the communication device by Bluetooth?, predetermined information for establishing a wireless connection of the communication device by Wi-Fi?.

There is provided an image communicating apparatus according to this invention. The image communicating apparatus determines whether to use a FAX server for FAX sending, adds, if it is determined to use the FAX server for the FAX sending, domain information of the FAX server to a destination of the FAX sending, and sends an image to the destination of the FAX sending, that has been added with the domain information.
