When a digital camera and printer are directly connected via a communication interface, and a recording process in the printer is interrupted while transmitting image data from the camera to the printer and recording the image data, the camera designates the restart of the recording process and it is determined whether the printer is of a type capable of restarting the recording process. In a case where the printer is determined to be the type capable of restarting the recording process and a DPOF (digital print order format) file is being printed, the DPOF file is resent to designate printing from a page next to the printed page. In a mode in which image data are sequentially transmitted to the printer and printed, a print process of image data subsequent to the printed image data is designated.
