A printing apparatus includes a printer engine and a network interface. A first controller communicates with the network interface, and a second controller controls power supply to the printer engine and the first controller. The first controller, when the printing apparatus makes a transition to a power-saving state, causes the network interface to be in a first sleep state or a second sleep state from the normal operation state and instructs the second controller to stop power supply to the first controller. The second controller supplies power to the first controller when the printing apparatus resumes from the first sleep state, and supplies power to the first controller and the printer engine when the printing apparatus resumes from the second sleep state.

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 printing device includes a printing device side wireless communication unit configured to execute wireless communication with a mobile terminal, an operation acquisition unit configured to acquire user operation thereof, and a processor. The processor is configured to acquire operation data which is generated as the operation acquisition unit acquires a user operation, acquire establishment data which is generated as the printing device side wireless communication unit establishes a wireless communication with the mobile terminal, and issue a request control to control the printing device side wireless communication unit to transmit request data requesting the mobile terminal to transmit print data necessary for printing, via the wireless communication, when the establishment data is acquired, the request control being issued in accordance with the operation data as acquired.

According to this invention, in a reception end facsimile apparatus having a first communication mode for performing communication at a high speed and a second communication mode for performing communication at a low speed, it is determined based on an instruction from a transmission end facsimile apparatus whether to perform error correction during facsimile communication. Control is done not to perform communication in the first communication mode based on a fact that it is determined not to perform error correction during facsimile communication.

A communication device may receive a first specific signal from a terminal device via an NFC interface, determine whether the first specific signal includes install information, change an operation mode of the NFC interface from Reader mode to CE mode in a case where it is determined that the first specific signal does not include the install information, change the operation mode of the NFC interface from Reader mode to Writer mode in a case where it is determined that the first specific signal includes the install information, supply first identification information to the NFC interface in a case where the NFC interface operates in CE mode, and supply specific information different from the first identification information to the NFC interface in a case where the NFC interface operates in Writer mode.

Various embodiments of the present disclosure are directed to a communication apparatus capable of preventing a decrease in the speed of communication with an external device due to execution of a handover when the communication apparatus is connected to the external device, and also directed to a control method and a recording medium. A communication apparatus provides, by using a first communication portion that uses a first communication method, communication information for performing communication based on a second communication method to an external device, and causes a second communication portion that uses the second communication method to connect with the external device using the second communication method, and performs control in such a manner that, in a case where the second communication portion connects with the external device, the first communication portion is used to provide communication information to no other external devices.

An information processing apparatus includes plural communication units, a switching unit, and a controller. The communication units are configured to conduct a wireless communication. The switching unit is configured to switch a first communication unit having a relatively fast communication speed to a second communication unit having a relatively slow communication speed if a communication is attempted to start and if the first communication unit is being used. The controller is configured to perform a control to start the communication by the first communication unit.

An information processing apparatus executes, for image data to be printed by a printing device, image processing corresponding to a content of the image data; transmits, to the printing device, image data obtained after executing the image processing; acquires, before executing the image processing, a first transfer rate with respect to the printing device and a requested transfer rate required by a print operation of a print unit of the printing device; attempts image processing for the image data; and acquires, based on the first transfer rate and information of image data obtained after the attempt, a second transfer rate required by transmission, to the printing device, of the image data obtained after the attempt and the print operation of the print unit.

An information processing apparatus coupled to a device via at least one of a plurality of networks includes a memory having computer readable instructions and at least one processor configured to execute the computer readable instructions to transmit to the device first communication information for performing communication between the device and the information processing apparatus, when a process is requested from the device; determine whether the communication is possible via a first network to which the device is coupled according to whether the communication is performed using the first communication information; connect to a second network using second communication information for connecting to the second network, when the communication is determined impossible via the first network; and determine whether the communication is possible via the second network according to whether the communication is performed using the first communication information via the second network.

This disclosure relates generally to communicating video content and other data over networks. An example apparatus includes a transmitter for communicating data via a serial link with a receiver. The transmitter includes an input, an output interface to the serial link, and translation circuitry. The input includes multiple input data lanes and a clock lane, and the input is configured to concurrently receive data on the multiple input data lanes aligned with a clock signal received on the clock lane according to a multi-lane communication protocol. The output interface is a clock-less interface and includes a number of output data lanes less than a number of the multiple input data lanes. The translation circuitry translates the data received according to the multi-lane communication protocol to a serial link communication protocol for transmission on the serial link.
