An information processing apparatus includes a wireless interface configured to perform communication with an image forming apparatus, and at least one controller configured to function as a unit configured to acquire device information of the image forming apparatus from the image forming apparatus through the wireless interface, and a unit configured to selectively accept one of a first instruction to transmit the acquired device information to an external destination and a second instruction not to transmit the acquired device information to the external destination. The controller also functions as a unit configured to transmit, in a state where the first instruction has been accepted, the acquired device information to the external destination, and hold, in a state where the second instruction has been accepted, the acquired device information without transmitting the acquired device information to the external destination.

A communication apparatus comprises: a sending unit that sends data to a designated destination; a receiving unit that receives a response to the send by the sending unit; a recording unit that records information relating to a send when the send is performed by the sending unit, and associates and records, when a response to the send is further received by the receiving unit, information of a send-source of the response; and a control unit that causes the sending unit to resend data based on information recorded in the recording unit, wherein the control unit causes the sending unit to resend data to a destination indicated by information, among the recorded information, for which a predetermined time has elapsed since the recording and for which a response has not been received by the receiving unit.

An acquisition unit acquires device information of an image forming apparatus from the image forming apparatus. A first acceptance unit selectively accepts one of an instruction to transmit the device information to an external unit and an instruction to hold the device information in the information processing apparatus. A transmission control unit transmits, if the first acceptance unit accepts the instruction to transmit the device information to the external unit, the device information to the external unit, and hold, if the first acceptance unit accepts the instruction to hold the device information in the information processing apparatus, the device information in the information processing apparatus without transmitting the device information to the external unit.

There is provided an image processing apparatus that transmits data relating to an internal component to a server via a network, and the image processing apparatus includes a hardware processor that: acquires the data relating to the internal component; judges whether or not it is a transmission timing at which the data acquired is to be transmitted to the server; confirms an operation state of another image processing apparatus connected to the network in a case where it is judged that it is the transmission timing; decides whether or not to transmit the data acquired to the server based on a confirmation result; and transmits the data acquired to the server in a case where it is decided to perform data transmission.

A communication control device includes a communication unit, an acquiring unit, and an adjusting unit. The communication unit transfers first image data acquired from a first processing unit to an external controller of a system, receives second image data transferred from the external controller during an interval between pieces of the first image data transferred in predetermined units, and transfers the received second image data to a second processing unit. The system includes the communication control device and the external controller connected to the communication control device by a half-duplex communication line. The acquiring unit acquires a length of a transfer period for transferring the second image data. The adjusting unit adjusts timing of acquiring the first image data in accordance with the length of the transfer period acquired by the acquiring unit.
