A communication apparatus for data communication with a plurality of external devices includes a communication interface and processing circuitry. The communication interface is configured to perform wired communication and wireless communication with the plurality of external devices. The processing circuitry is configured to determine whether the plurality of external devices is connected via the wired communication or the wireless communication, and switch a connection destination from one external device to another external device of the plurality of external devices when the one external device is connected via one of the wired communication and the wireless communication and the processing circuitry receives a connection request from said another external device via the other of the wired communication and the wireless communication.

Apparatus and method for switching connection destination between external devices

A handheld printing apparatus includes a memory and processing circuitry. The memory is configured to store a plurality of pieces of image data. The processing circuitry is configured to print the plurality of pieces of image data one by one in an order. The processing circuitry is configured to print one piece of image data by one scan and switch a piece of image data to be printed, in the order among the plurality of pieces of image data, each time one scan ends.

Printing apparatus, printing system, and printing method

A liquid discharge apparatus includes a head configured to discharge liquid to print an image on a recording medium according to image data while the liquid discharge apparatus is moved; a sensor configured to detect movement of the liquid discharge apparatus in a predetermined period and output movement information including at least one of a movement amount and an angular velocity of the liquid discharge apparatus; a heater configured to heat the head; a temperature sensor configured to detect a temperature of the head; and circuitry. The circuitry is configured to instruct liquid discharge from the head based on the image data and the movement information from the sensor, detect floating of the liquid discharge apparatus based on a detection result generated by the sensor, and control heating of the head based on a result of detection of the floating.

Liquid discharge apparatus and liquid discharge method

An equipment controller is disclosed that includes a CPU instructed to switch to a low power mode when being in a non-execution state. The equipment controller determines whether there is any execution task when the state of equipment switches to an energy-saving mode in which consumption power is reduced, and sets the interrupt cycle of a system timer of a real time OS that generates an interrupt for causing the CPU to awaken to be long if there is no execution task so that the CPU is caused to switch to the low power mode.

Equipment controller, image forming apparatus, and method for controlling equipment

In the printing apparatus according to the present invention, the central processing section determines as to whether an empty area required for loading of image data is available in a swap page used as a swap area of a real page or not, and directly loads the image data on the swap page and compresses the image data when an empty area is available in a memory of the swap page. On the other hand, when an empty area is not available, the central processing section loads the image data in a real page via a virtual frame buffer and transfers the image data to the swap page for compression thereof.
