In a direct print system comprised of a digital still camera and a photo-direct (PD) printer, it makes possible to confirm and change printing layout from the digital still camera so as to obtain a printing result satisfying a user's wish in multi-partitioned print that a plurality of images are printed on a paper sheet. Both of the digital still camera and the PD printer respectively have a decoder and an encoder for commands of PictBridge format, and both of the digital still camera and the PD printer can recognize predetermined comments written in comment lines of the PictBridge which are normally ignored. When the multi-partitioned print is selected by the user, commands appointing order of arrangement and directions of the images to be printed are written on the comment lines of the PictBridge and transmitted with a command of the PictBridge format for performing the multi-partitioned print from the digital still camera to the PD printer.
