Information processing apparatus capable of responding to image transmission request issued before image accumulation, method of controlling same, image processing system, and storage medium

An image processing system including an information processing apparatus and an image processing apparatus communicably connected to each other,

• the information processing apparatus comprising:
• at least one processor;
• and
• a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, perform the operations as:
• a transmission unit configured to transmit a request for transmitting an image to the image processing apparatus;
• a monitoring unit configured to monitor whether or not an image associated with the transmission request has been received;
• and
• a control unit configured to control the monitoring unit to start monitoring of whether or not an image associated with the transmission request has been received in response to receiving information indicating that there is no image associated with the transmission request, as a response to the transmission request,
• wherein in a case where there is no image associated with the transmission request, the image processing apparatus transmits the information indicating that there is no image associated with the transmission request to the information processing apparatus.

A method of controlling an information processing apparatus, comprising:

• transmitting a request for transmitting an image to an image processing apparatus;
• monitoring whether or not an image associated with the transmission request has been received;
• and
• starting monitoring of whether or not an image associated with the transmission request has been received, in response to receiving information indicating that there is no image associated with the transmission request, as a response to the transmission request.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling an information processing apparatus,

• wherein the method comprises:
• transmitting a request for transmitting an image to an image processing apparatus;
• monitoring whether or not an image associated with the transmission request has been received;
• and
• starting monitoring of whether or not an image associated with the transmission request has been received, in response to receiving information indicating that there is no image associated with the transmission request, as a response to the transmission request.
