A control system includes a terminal device including a first communication unit configured to perform first Bluetooth communication and second Bluetooth communication, and a printing apparatus including a second communication unit that is connected by pairing to the terminal device to perform the second Bluetooth communication with the first communication unit, wherein the terminal device performs the first Bluetooth communication in a state where no pairing connection is made with the printing apparatus, and transmits a notification instruction command to the printing apparatus through the first communication unit, and wherein the printing apparatus performs a notification operation based on the notification instruction command when receiving the notification instruction command through the second communication unit based on the first Bluetooth communication.

A printing system includes: a printer including a controller; and a contract processing server. The controller is configured to perform: determining, in response to receiving from an external device a print job including print data representing an image, whether authority information indicating an authority to print the image has been issued; and transmitting, in response to determining that the authority information has been issued, to the contract processing server an inquiry for determining whether the authority information is valid. The contract processing server is configured to perform: transmitting, in response to receiving the inquiry, a response to the controller. The controller is configured to further perform: determining, in response to receiving the response, whether the authority information is valid on the basis of the received response; and printing, in response to determining that the authority information is valid, the image on a print medium by controlling the printer.

A control unit is configured to perform second control for stopping operation in a predetermined mode based on a second time shorter than a first time, the second time having elapsed with connection setting not made since the operation in the predetermined mode by a communication apparatus was started in a case where the communication apparatus is operating in the predetermined mode and the predetermined processing is completed.

Convenience and security of an information processing apparatus including a USB host interface in a case where network connection is established via a USB-LAN adapter are improved. The information processing apparatus includes a plurality of external USB ports to which USB compatible network adapters are connected. The information processing apparatus performs a predetermined notification in response to a number of the network adapters connected to the information processing apparatus via the external USB ports having reached a predetermined upper limit.

An example system may include a plurality of print devices, a supply attachment, and a device remote to the plurality of print devices. The plurality of print devices may receive the supply attachment. The device remote to the plurality of print devices may receive signals via the supply attachment that are indicative of print device information data from the plurality of print devices.

An appliance management system includes a plurality of appliances connected to a network and a portable terminal. Each of the appliances includes a sensor configured to detect an abnormality of the appliance, and a first near field wireless communication module configured to broadcast an identifier of the appliance when the sensor detects the abnormality. The portable terminal includes a second near field wireless communication module and a controller. The controller is configured to control the second near field wireless communication module to transmit an access request to an abnormal appliance upon the second near field wireless communication module receiving an identifier of the abnormal appliance. The terminal controller is also configured to control a display to display an abnormality screen including the identifier of the abnormal appliance upon the second near field wireless communication module receiving abnormality information from the abnormal appliance.

A method is provided to exert unbinding control on an image forming device. The method includes: obtaining an unbinding instruction; sending a first unbinding request to the server according to the unbinding instruction, where the unbinding request includes identification information of the image forming device; obtaining a reply message from the server in response to the unbinding request; and in response to a determination that the reply message indicates unbinding failure, automatically sending a second unbinding request to the server.

A peer-to-peer network of printing devices is configured to share printing device information, such as job queue status, configuration information, and resource information for automated load balancing, capability matching, failover, and print splitting operations. A digital front end (DFE) of a printing device establishes connections with the DFEs of other printing devices to manage output within the peer-to-peer network in an automated manner. When a print job is received at a DFE for a printing device, it is evaluated to determine how to best manage the output for the print job.

A communication system comprising an information processing apparatus and a mobile terminal, wherein when the mobile terminal receives a packet transmitted from the information processing apparatus, it determines whether or not a login condition for transmitting a login request is satisfied based on a received signal strength of the packet, and it transmits the login request to the information processing apparatus in a case where it determines that the login condition is satisfied, and does not transmit the login request to the information processing apparatus in a case where it is determines that the login condition is not satisfied.

A print system includes a printing apparatus to print content according to a print job, and a server system to provide at least one of video information or still image information for an online class to a client terminal as distribution information. The client terminal receives notification information indicating that printable study material for an online class is present as the print content, and a print job for printing the study material is issued.
