An image forming apparatus performs: storing activation application specifying information that specifies an application to be activated on an operating system of an operation unit when the image forming apparatus enters a given state; notifying a main unit of the activation application specifying information; storing the notified activation application specifying information; controlling activation of an application to be activated by then operation unit, which is the application specified with reference to the activation application specifying information according to a state of the image forming apparatus, performing control to cause a display unit to display a screen for accepting an operation on the activated application, and controlling activation of an application to be activated by the main unit, which is the application specified with reference to the activation application specifying information according to the state of the image forming apparatus.

An information processing apparatus includes an image processing section that executes image processing, the operation control section that controls an operation of the information processing apparatus in any of two or more operation states including at least a first operation state, in which operations by all functions of the information processing apparatus are possible, and a second operation state in which operations by some functions of the information processing apparatus are limited, and the data processing section that executes specific data processing, which does not involve the image processing by the image processing section, in a case where the operation control section performs control in the second operation state.

The printing apparatus according to the present invention includes: a printing unit configured to form an image on a printing medium by using a color material and to output the printing medium on which the image is formed; a printing control unit configured to control the printing unit and to store data relating to the printing unit; a power control unit configured to control supply of power to the printing unit and the printing control unit; and a main control unit connected with the printing control unit so as to be capable of communication, and in accordance with a predetermined request, the power control unit performs control so as to suspend supply of power to the printing unit, the main control unit starts acquisition of the data stored by the printing control unit, and the power control unit performs control so as to suspend supply of power to the printing control unit after the main control unit completes acquisition of the data.

A communication control method which prevents control over a USB device from being hampered and reducing power consumption at the same time. When the USB device and a control apparatus, which controls the USB device, are connected to the printing apparatus, and a communication via the printing apparatus is being carried out, the printing apparatus and the USB device are not shifted into a power saving mode in which energization of the printing apparatus and the USB device is limited. When the USB device and the control apparatus are connected to the printing apparatus, and a communication via the printing apparatus is not being carried out, the printing apparatus and the USB device are shifted into the power saving mode.

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, when condition information does not include trigger information, determine to instruct the printer to start a pre-printing operation, when the condition information includes the trigger information, determine not to instruct the printer to start a pre-printing operation, 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 performing the preparation instruction process, generate print data based on specified contents data, and transmit the print instruction information to the printer.

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.

There is provided a technique of appropriately shifting an image forming apparatus to a power saving state in consideration of the use status of an external device such as a connected USB device. When a condition for shifting to a sleep state is satisfied, the CPU of the image forming apparatus determines whether or not a setting of a sleep shift at the time of use of the USB device is “permit”. If it is determined that the setting of the sleep shift at the time of use of the USB device is “do not permit”, the CPU determines whether or not the connected USB device is in use. If it is determined that the USB device is not in use, the CPU shifts the image forming apparatus to the sleep state.

An apparatus determines, when receiving a packet transited via a network in a power saving mode, whether or not the packet is a packet according to a predetermined protocol. If the packet is determined to be the packet according to a predetermined protocol, the apparatus analyzes the data of a succeeding packet described in a data description language, and instructs the apparatus to return from the power saving mode to a normal power mode depending on an analysis result.

An image forming system that is capable of preventing obstruction of transmission of a packet to an information processing apparatus from a USB device supporting USBNW due to the shift to the sleep mode. The image forming system includes an information processing apparatus, an image forming apparatus with a sleep mode, and a USB device that is connected to the information processing apparatus through the image forming apparatus and is controlled by the information processing apparatus. The image forming apparatus includes a first determination unit that determines whether the USB device supports USBNW, a second determination unit that determines whether a packet received from the information processing apparatus is processed by a module supporting USBNW, and a control unit that prohibits the image forming apparatus from shifting to the sleep mode when the USB device supports USBNW and when the packet is processed by the module supporting USBNW.

A control device is provided and includes: an acquisition unit that acquires the number of persons from a count unit, the count unit counting up the number of persons in an area based on a detection result of a first detection unit, the first detection unit detecting a person who goes in and out through an entrance of the area; and an operation mode control unit that controls an operation mode of a processing device according to the acquired number of persons.
