A list of processing data and the number of times of processing is notified to another electronic device to cause the another electronic device to perform data processing. When an error occurs in the another electronic device, a re-processing request of unprocessed data is formed again together with a list and notified. At this time, a printing state of a printer is designed to be determined and displayed by an image pickup device. When an image which is not printed is designated to be re-printed when an error occurs in the printer, a list of an image designated to be re-printed and the number of prints is re-formed and re-notified. Communication of printing data is performed by Bluetooth communication.
