Image processing apparatus and method of controlling the same

An image processing apparatus capable of communication with an external apparatus, the image processing apparatus comprising:

• a network interface that receives a shutdown request from the external apparatus;
• a controller, having at least one processor which executes instructions stored in a memory, one or more circuitry, or, a combination of the at least one processor and the one or more circuitry, being configured to:
• determine whether or not the image processing apparatus is capable of data transmission and reception via a fax line;
• and
• control to perform shutdown processing, when the network interface has received the shutdown request,
• wherein the controller does not execute the shutdown processing based on the shutdown request when it is determined that the data transmission and reception via the fax line is possible, and
• wherein the controller executes the shutdown processing of the image processing apparatus based on the shutdown request when it is determined that the data transmission and reception via the fax line is not possible.

A method of controlling an image processing apparatus capable of fax communication with an external apparatus, the method comprising:

• accepting from a user, in advance of receiving a shutdown request for executing shutdown processing of the image processing apparatus from an external apparatus via a network, a setting of whether or not to perform the shutdown processing based on the shutdown request received when the image processing apparatus is in a state of being connected to a line for fax communication and when fax communication is possible;
• and
• receiving the shutdown request from the external apparatus via the network;
• executing, in accordance with the setting accepted in advance from the user, the shutdown processing of the image processing apparatus based on the shutdown request received from the external apparatus.

A method of controlling an image processing apparatus capable of communicating with an external apparatus, the method comprising:

• receiving a shutdown request from the external apparatus;
• determining whether or not the image processing apparatus is capable of data transmission and reception via a fax line;
• and
• performing control to, when the shutdown request is received, not execute shutdown processing based on the shutdown request in a case that it is determined that the data transmission and reception via the fax line are possible, and execute the shutdown processing of the image processing apparatus based on the shutdown request in a case that it is determined that the data transmission and reception via the fax line are not possible.
