Abstract
According to an embodiment of this invention, there is provided a method in which even if, in an environment where an information processing apparatus and an image processing apparatus are connected by USB, communication from the information processing apparatus is terminated midway, processing on the image processing apparatus side is terminated. In this method, an HTTP communication module transmits, to the image processing apparatus, request information including information for identifying communication with the image processing apparatus. If response information, from the image processing apparatus, corresponding to the request information does not match the transmitted request information, the HTTP communication module transmits an instruction to operate the image processing apparatus in a status in which it is possible to transmit the response information.
