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 transmission apparatus includes a scanner. A first control is performed about reading of a plurality of pages of documents by using the scanner to generate image data. A second control is performed about conversion processing of the generated image data. A third control is performed about transmission of processed data on which the conversion processing is performed. The third control includes starting a session while a document is being read based on the first control, and transmitting, to an external apparatus via a network, the processed data on which conversion is already performed. Where an error occurs in the scanner in reading the documents, the third control further includes disconnecting the started session. Where the error is resolved, the third control further includes connecting the session again and transmitting, to the external apparatus via the network, processed data on which the conversion processing is performed.

A method and a device for controlling image-forming devices, and an electronic terminal using the method are provided in the present disclosure. The method includes acquiring currently-available wireless networks; when a wireless network is provided by an image-forming device, acquiring a first network identifier of the wireless network; when a wireless network is not provided by the image-forming device, connecting to the wireless network and acquiring a first device identifier of the image-forming device connected to the wireless network; adding the first network identifier and the first device identifier acquired to the list of the image-forming devices; according to the list of the image-forming devices, selecting a target image-forming device; and connecting to a wireless network corresponding to the target image-forming device and establishing a communication with the target image-forming device, thereby controlling the target image-forming device to execute an image-forming task.

On a display unit, a user interface screen including a first acceptance unit configured to, in a case when the information processing apparatus is operating as an access point, accept an end instruction for ending operation as the access point and a second acceptance unit configured to accept a disconnection instruction for disconnecting the connection by the wireless communication with the terminal is displayed.

An information processing apparatus controls a printing process performed by an image forming apparatus. The information processing apparatus includes a communication controller configured to perform communication with the image forming apparatus; a display controller configured to cause a display to display an operation screen for accepting a setting or an operation relating to the printing process; a data transmitter configured to transmit predetermined data by the communication to the image forming apparatus, while the operation screen is being displayed; and a renderer configured to generate print data to be transmitted to the image forming apparatus by the communication, according to the setting or the operation accepted at the operation screen.

A transmission apparatus includes a scanner. A first control is performed about reading of a plurality of pages of documents by using the scanner to generate image data. A second control is performed about conversion processing of the generated image data. A third control is performed about transmission of processed data on which the conversion processing is performed. The third control includes starting a session while a document is being read based on the first control, and transmitting, to an external apparatus via a network, the processed data on which conversion is already performed. Where an error occurs in the scanner in reading the documents, the third control further includes disconnecting the started session. Where the error is resolved, the third control further includes connecting the session again and transmitting, to the external apparatus via the network, processed data on which the conversion processing is performed.

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.

An apparatus and a method are provided. The method includes measuring, by a mobile terminal, a signal strength of advertising packets broadcast by an image forming apparatus, determining whether the measured signal strength decreases for at least a preset period of time, and, when the signal strength decreases for at least the preset period of time, transmitting a logout request to the image forming apparatus.

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 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.
