摘要

PROBLEM TO BE SOLVED: To suppress wasteful power consumed in a system when communication between a network and the system is cut off.SOLUTION: When an image processing device 110 detects a cut-off state of communication with a network 130 (no in S501), the image processing device 110 instructs an image output device 120 to shift to a power off state (S505), and shifts the image processing device 110 itself to the power off state (S509). The image output device 120 shifts the image output device 120 itself to the power off state according to the shift instruction to the power off state from the image processing device 110.
