A printing apparatus including: a printing unit configured to perform printing on a printing medium; and a controller, wherein the printing apparatus is configured to perform communication with an external mediation apparatus configured to perform communication with a management server via the Internet, and wherein the controller is configured to: try to acquire time information necessary for encrypted mutual recognition communication; determine whether the time information has been successfully acquired; and not executing information transmission and reception with respect to the external mediation apparatus by the mutual recognition communication in a case where the determining does not determine that the time information has been successfully acquired, and execute the information transmission and reception with respect to the external mediation apparatus by the mutual recognition communication in a case where the determining determines that the time information has been successfully acquired.

An image forming apparatus including a storage device storing, from among data to be retained when the power is shut off, either or both of important protection data, being a type determined to be important in advance, and protection data, to be retained when the power is shut off other than the important protection data, at respective predetermined timings. A detection information acquirer receives detection information from a sensor detecting at least one of: a change in either or both of direction and tilt, vibration, a predetermined operation, an approaching person, a person entering a room, and a person entering a predetermined area. A protection processor starts processing for writing either or both of the important protection data and the protection data into the storage device in response to the detection information received by the detection information acquirer, at timings different from the predetermined timings.

An MFP communicates with a DNS server through a network. This MFP includes an operation unit that sets whether a printing service is activated or not and a controller unit that registers search information in which capability information provided for a client terminal and information relating to name resolution are associated with each other in the DNS server in accordance with activation of the printing service being set by this operation unit.

A printing system includes a printer and an information processing device that includes a processor and a memory storing processor-executable instructions, the instructions being configured to, when executed by the processor, cause the processor to accept a print instruction, in response to accepting the print instruction, determine whether to instruct the printer to start a pre-printing operation based on preparation instruction information, in response to determining to instruct the printer to start the pre-printing operation, transmit the preparation instruction information to the printer, in response to determining to instruct the printer to start the pre-printing operation and transmitting the preparation instruction information to the printer, generate print data based on specified contents data, and transmit print instruction information to the printer.

An image reading apparatus includes a first posture detection unit that detects a first posture that is a posture of the apparatus main body when not in use, a second posture detection unit that detects a second posture that is a posture of the apparatus main body when in use, and a posture change detection unit that detects a change in a posture of the apparatus main body. When the first posture detection unit detects a switchover of the apparatus main body to the first posture in a first power supply mode in which power is supplied to the first posture detection unit, the second posture detection unit, and the posture change detection unit, the first power supply mode transitions to the second power supply mode in which a controller supplies power to only the posture change detection unit.

An apparatus includes: an operation panel that displays an operation screen and accepts an operation from a user; a hardware processor that accepts an operation from a user by voice, turns off the operation panel in a case where an interval between operations received by the operation panel exceeds a first set time, and resets a setting content stored in the storage in a case where an interval between operations received by the operation panel or the hardware processor exceeds a second set time; a storage that stores a setting content corresponding to an operation received by the operation panel or the hardware processor; and a changer that changes a set time of a timer.

The multifunction machine includes a first CPU core that performs an operation in a normal mode and suspends an operation in an energy saving mode, a second CPU core that performs an operation in the energy saving mode, and a storage unit that stores time information for determining a timing of performing a keep-alive process, wherein the first CPU core causes the operation mode to transition to the normal mode when acquiring a normal mode transition instruction from the second CPU core in the energy saving mode, and then, performs a keep-alive process for the remote operation server, and wherein the second CPU core gives the normal mode transition instruction to the first CPU core based on the time information in the energy saving mode.

A semiconductor device includes a load element, a switching element, and a processor. The load element controls a temperature of the semiconductor device with an electric current supplied to the load element. The switching element switches between supply of an electric current to the load element and a cut-off of the supply. The processor controls the switching element. The processor controls the electric current to be supplied to the load element through the switching element so that the semiconductor device has a series of temperatures represented by a specific temperature profile.

An printing apparatus includes a printer configured to print an image on a printing medium, a network interface configured to receive, from an external device, a print job to be held, a memory configured to store the print job received by the network interface, and a user interface configured to accept, from a user, an execution instruction for the print job stored by the memory. In addition, a controller controls the printer to print based on the print job in accordance with the execution instruction accepted by the user interface, and a power controller performs control so that power is supplied to a predetermined device of the printer based on a reception of the print job by the network interface.

An image forming apparatus includes an image forming unit configured to form an image on a sheet based on image data, a control unit configured to control driving of the image forming unit, and a power supply unit configured to, if a factor for shifting from a power saving state to a standby state is detected, supply power to the image forming unit and the control unit. If a first type of factor is detected as the factor in the power saving state, the power supply unit supplies power to the control unit and the image forming unit, and the control unit restricts the driving of the image forming unit. If an instruction to perform a function of forming an image on a sheet is accepted, the control unit cancels restriction of the driving of the image forming unit.
