A first communication apparatus may repeat a broadcast transmission of a trigger signal via a second interface, which is a signal to be used by a second communication apparatus as a trigger for sending a wireless connection request to the first communication apparatus. The wireless connection request may be for forming a first wireless network to which both the first communication apparatus and the second communication apparatus belong. The first wireless network may be a network for performing a wireless communication via a first interface The first communication apparatus may receive the wireless connection request via the first interface from the second communication apparatus which has received the trigger signal, and establish a first wireless connection via the first interface with the second communication apparatus so as to form the first wireless network.

A controller is configured to control an image reading apparatus to a first connected state in which the image reading apparatus is connected to an external apparatus by a first connection method by which the image reading apparatus is connected to the external apparatus in a one-to-one relationship via a single communication path, and to a second connected state in which the image reading apparatus is connected to the external apparatus by a second connection method by which the image reading apparatus is connectable to a plurality of external apparatuses in a one-to-many relationship via a single communication path. The controller disables disconnection processing of disconnecting the image reading apparatus from the external apparatus to be performed when a first time period elapses without the image reading apparatus being operated in the first connected state, and enables the disconnection processing to be performed when the first time period elapses without the image reading apparatus being operated in the second connected state.

A process, machine-readable instructions, and a system are described in which two communication sessions are attempted to be established between a client application and an image processing apparatus. In some examples, the first communication session is permitted while delaying the operation of the second communication session until the first communication session has completed.

Provided is an operating method of an image forming apparatus, the operating method including broadcasting a plurality of packets comprising identification information of the image forming apparatus; receiving a connection request comprising the identification information of the image forming apparatus from a mobile terminal which received some packets from among the plurality of broadcasted packets; and connecting to the mobile terminal, based on the connection request, wherein the connection request is transmitted from the mobile terminal when received signal strengths of the some packets received by the mobile terminal are equal to or greater than a first threshold value. In this regard, the first threshold value may indicate a received signal strength greater than a minimum received signal strength at which communication with the mobile terminal is available.

A communication apparatus may determine whether specific apparatus identification information for identifying a specific external apparatus is stored in a memory in a case where the specific apparatus identification information is received via a second interface from the specific external apparatus, shift an operating state of the communication apparatus from a non-parent station state to a parent station state in a case where it is determined that the specific apparatus identification information is stored in the memory, receive a wireless connection request from the specific external apparatus via a first interface after the operating state has been shifted from the non-parent station state to the parent station state, and form the wireless network in which the communication apparatus operates as the parent station and the specific external apparatus operates as a child station, in a case where the wireless connection request is received from the specific external apparatus.

A mobile information processing apparatus includes a receiver and a transmitter. The receiver receives destination information via visible light communication. The destination information is information for identifying an image output apparatus as a destination of second communication different from the visible light communication. The transmitter transmits second information and a print instruction to the image output apparatus via the second communication in accordance with the destination information. The second information is information indicating receipt of the destination information by the receiver.

A printer includes a printer-side memory that stores first connection setting information for establishing a communication connection with one or a plurality of terminal devices, and in accordance with second connection setting information for establishing a communication connection with an access point received from the terminal device with which a communication connection has been established, a printer-side processor that establishes a communication connection with the access point, wherein when the printer-side processor determines the terminal device having a communication connection to be the terminal device connected by mistake, disconnects the communication connection with the terminal device, and changes the first connection setting information stored in the printer-side memory.

An image processing device includes: a hardware processor configured to: execute a process according to a received remote operation in response to reception of the remote operation from a master device registered in advance among a plurality of mobile information devices; confirm to a duplicate login device other than an own device among the plurality of image processing devices that the duplicate login device is remotely operated by the master device in a case where a remote operation of instructing connection with a sub device different from the master device is received from the master device; and execute a process according to a remote operation received from the sub device in a case where it is confirmed by a confirmation unit that the duplicate login device is remotely operated by the master device.

A communication apparatus may determine whether specific apparatus identification information for identifying a specific external apparatus is stored in a memory in a case where the specific apparatus identification information is received via a second interface from the specific external apparatus, shift an operating state of the communication apparatus from a non-parent station state to a parent station state in a case where it is determined that the specific apparatus identification information is stored in the memory, receive a wireless connection request from the specific external apparatus via a first interface after the operating state has been shifted from the non-parent station state to the parent station state, and form the wireless network in which the communication apparatus operates as the parent station and the specific external apparatus operates as a child station, in a case where the wireless connection request is received from the specific external apparatus.
