A facsimile transmission system includes circuitry to receive, from a user, a request for facsimile transmission of a document, and determine which one of first facsimile transmission and second facsimile transmission is to be performed, based on one of an attribute of the user, an attribute of a destination of the facsimile transmission, and an attribute of the document. The first facsimile transmission is transmitting the document by an image forming apparatus, and the second facsimile transmission is transmitting the document by a facsimile server. The circuitry further instructs to perform the one of the first facsimile transmission and the second facsimile transmission.

A method for controlling a communication apparatus includes receiving a transmission destination, acquiring identification information of a user who inputs a transmission destination of image data, requesting identification information of a checker for the transmission destination, acquiring the requested checker identification information, and storing the acquired user identification information and the acquired checker identification information as transmission history information of the image data.

An underwater communications system includes a network communication interface, one or more computer processors, and a memory containing computer program code that, when executed by operation of the one or more computer processors, performs an operation. The operation includes storing a plurality of data packets to be transmitted to a destination device, determining that data communications over the network communication interface have become available for a first network node, and determining that the first network node has a valid security credential that has not been revoked by an access granting authority. Additionally, the operation includes, upon determining that the first network node has the valid security credential, transmitting the stored plurality of data packets over the network communication interface to the first network node. The first network node is configured to employ store-carry-and-forward data messaging techniques to transmit the plurality of data packets towards the destination device.

An image forming apparatus can include a communications circuit, a printer, and a controller. The communications circuit is configured to communicate with a networked image forming apparatus via a network. The printer is configured to form an image on a sheet. The controller includes a processor and a memory. The controller is configured to acquire sensor data from a sensor operatively coupled to the controller; determine, via the network, a relay image forming apparatus, the relay image forming apparatus having an operating rate being relatively lower than an operating rate of multiple image forming apparatuses including the image forming apparatus and the networked image forming apparatus; and transmit, via the relay image forming apparatus, the sensor data to a predetermined recipient apparatus.

A device management system and a device management method are provided, each of which: receives status information indicating a status of a relay device from the relay device, the relay device being connected with one or more devices in a local network via a firewall; based on a determination that the received status information satisfies a predetermined condition, obtains instruction information associated with the predetermined condition, the instruction information indicating a predetermined process to be executed by the relay device; and transmits the obtained instruction information to the relay device to cause the relay device to execute the predetermined process.

Provided is a data transmission system that accurately performs transmitting and receiving of job data. A cloud server transmits job data, a vibration-detection sensor of a gateway detects vibration that is applied to the gateway, a vibration-detection sensor of an MFP detects vibration that is applied to the MFP, the gateway stores job data that is received from the cloud server in memory of the gateway, and then transmits the job data to the MFP. Moreover, the gateway, when the value of vibration-detection data of the vibration-detection sensor is equal to or less than a specified threshold value, stores the job data from the cloud server in memory, and when the value of vibration-detection data of the vibration-detection sensor equal to or less than a specified vale, transmits the job data that is stored in memory to the MFP.

An image forming apparatus and a method for transmitting a fax using an application are provided. The image forming apparatus includes a communicator to perform communication with an external device, a fax unit to receive a fax document through a public switched telephone network, a memory in which an application for routing the received fax document is installed, and a controller to execute the application installed in the memory, to select, based on an attribute of the fax document, a device to which the fax document is to be transmitted, and to transmit the fax document to the selected device via the communicator.

A method for controlling a communication apparatus includes receiving a transmission destination, acquiring identification information of a user who inputs a transmission destination of image data, requesting identification information of a checker for the transmission destination, acquiring the requested checker identification information, and storing the acquired user identification information and the acquired checker identification information as transmission history information of the image data.

A remote communication control system includes a session relay system that associates a connection established with an image forming apparatus with a connection established with an electronic device located outside a network to which the image forming apparatus belongs, so as to relay a session between the image forming apparatus and the electronic device. When an application is unusable via the session, the session relay system does not relay the session based on a control policy and identification information of the application as a target for the session. The control policy indicates whether which application of the image forming apparatus is usable via the session.

Systems and methods for the virtualization, aggregation, enhancement, and distributed processing of facsimile communications. The Remote FAX Interconnect known as etherFAX is a system and method that allows for the reception and delivery of information to or from one or more facsimile systems using Internet/web based communication protocols such as HTTP(S) as the transport between a cooperating facsimile capable application or hardware and the remotely accessible etherFAX services.
