A communication device includes: a signal reception circuit to receive a differential signal and convert the differential signal into binary data; a squelch detection circuit to compare an amplitude level of the differential signal with threshold voltages to detect presence or absence of a signal and detect a non-squelch state and a squelch state; a start pattern detection circuit to enter a receivable state in response to a predetermined start pattern based on the differential signal; a register that stores a squelch setting value associated with the threshold voltages; a DC voltage selection circuit to select two DC voltages in accordance with the squelch setting value, and supply the two DC voltages to the squelch detection circuit; and a squelch setting control circuit to change the squelch setting value to increase or decrease the squelch setting value in steps and sequentially set the squelch setting value in the register.

A function executing device is configured to send a wireless identifier to a communication device via a first type of wireless communication interface for setting up a wireless connection. The function executing device is configured to determine whether the function executing device is in an error state and, if not, to establish the wireless connection via a second type of wireless communication interface. The function executing device operates in a parent state in the wireless connection. Additionally, print data may be received from the communication device. However, if the function executing device is in an error state the wireless connection is not established via the second type of wireless communication interface.

An information processing apparatus includes a switching unit and a controller. The information processing apparatus performs a data sending and receiving operation with an external apparatus via a data line which is compliant with a predetermined standard. The switching unit switches the information processing apparatus to a host device or a non-host device in accordance with a state of the information processing apparatus. The controller controls a data sending and receiving operation performed with the external apparatus. The controller controls a data sending and receiving operation for a host device when the information processing apparatus is switched to the host device. The controller controls a data sending and receiving operation for a non-host device when the information processing apparatus is switched to the non-host device.

An information processing apparatus capable of communicating with an external apparatus, comprises: an obtainment unit that obtains information from an external apparatus; a determination unit that determines an operation mode of the information processing apparatus; and a notification unit that performs a notification based on the information obtained by the obtainment unit, wherein the notification unit, if the mode determined by the determination unit is a specific operation mode, performs the notification based on the information obtained by the obtainment unit in a second notification screen that is smaller than a first notification screen, and, if the mode determined by the determination unit is not the specific operation mode, performs the notification based on the information obtained by the obtainment unit in the first notification screen.

A control device that executes an operating system program includes a hardware processor, wherein the operating system program defines a process of setting one image forming apparatus among a plurality of image forming apparatuses as a default device, and a changing process, in the case where an execution device different from the default device is designated from among the plurality of image forming apparatuses by an application task for executing an application program and printing is performed by the execution device, setting the execution device as the default device, and the hardware processor allows one control target device among the plurality of image forming apparatuses to perform printing in response to an instruction for printing given by the application task, and maintains the same image forming apparatus as the default device before and after printing is performed by the control target device.

A method, a computer readable medium, and a multi-function peripheral are disclosed, which use IPv6 packet extensions for execution of a job request based on proximity. The method including sending a job to be processed by a multi-function peripheral with an IPv6 Destination Options extension header from a client device to the multi-function peripheral, the IPv6 Destination Options extension header containing a physical location of the client device; receiving the job with the IPv6 Destination Options extension header containing the physical location of the client device on the multi-function peripheral; examining the IPv6 Destination Options extension header containing the physical location of the client device on the multi-function peripheral; and executing the job if the physical location of the client device is within a defined proximity to the multi-function peripheral.

A management server that manages a network device (e.g., an MFP) using NETCONF registers, in the MFP, designation of a condition under which the MFP is to notify the management server of an event, receives, from the MFP, a first notification indicating that a transition is made from a first state in which a session enabling the event notification is established to a second state in which the session needs to be disconnected and a second notification indicating return to the first state, and re-registers the designation of the condition in the MFP in response to reception of the second notification.

A wireless communication apparatus that operates on electric power supplied from a battery includes a first wireless communication unit that performs a first wireless communication, a second wireless communication unit that performs a second wireless communication that consumes less electric power than the first wireless communication, a battery's state detection unit that detects a state of the battery, and a first control unit that controls the first wireless communication unit and the second wireless communication unit. The first control unit determines which one of the first wireless communication and the second wireless communication to adopt as a wireless communication that is to be used for communication, on the basis of the state of the battery detected by the battery's state detection unit.

In an image forming apparatus, a reservation managing unit receives a reservation request from a mobile terminal device of a user, and registers reservation information. The reservation information indicates (a) a usage time zone specified by the received reservation request and (b) the mobile terminal device. The operation restriction unit changes an operation control mode from an operation permission mode to an operation prohibition mode if (a) the mobile terminal device detected by a terminal detecting unit is a mobile terminal device of a reserving user who reserved as the usage time zone a current or a next time zone and (b) there are no currently using users. The operation permission mode is a status where an operation of an unspecified user can be received, and the operation prohibition mode is a status where a user operation is prohibited until a release operation of the reserving user.
