A technique to give a more suitable screen to a user even when functions that can be executed by an image forming apparatus are provided by a linked external apparatus. A comparison unit of the external apparatus compares information about first functions of the external apparatus with information about second functions of the image forming apparatus. A determination unit of the external apparatus determines functions used by the image forming apparatus among the first functions based on a comparison result. A screen information sending unit of the external apparatus sends screen information used for setting the functions determined to the image forming apparatus. A functional information sending unit of the image forming apparatus sends the information about the second function to the external apparatus. A display unit of the image forming apparatus displays a screen for setting the first functions based on the screen information received from the external apparatus. |
