Abstract:
A communication control method which prevents control over a USB device from being hampered and reducing power consumption at the same time. When the USB device and a control apparatus, which controls the USB device, are connected to the printing apparatus, and a communication via the printing apparatus is being carried out, the printing apparatus and the USB device are not shifted into a power saving mode in which energization of the printing apparatus and the USB device is limited. When the USB device and the control apparatus are connected to the printing apparatus, and a communication via the printing apparatus is not being carried out, the printing apparatus and the USB device are shifted into the power saving mode.
