When an image is sensed by a digital camera, image additional information as the image sensing conditions is stored together with the sensed image information. Also, information unique to that digital camera is stored together with the image additional information. The digital camera is connected to a printer by, e.g., an IEEE1394 I/F. The printer stores printing control information as various combinations of unique information such as its printing method, the types of ink, paper, and the like, print quality and print speed, and processing technique such as masking. In response to a print instruction, the printer reads the image information and image additional information from the digital camera, and selects the printing control information in accordance with the read information and the set printing mode. The printer prints an image using the selected printing control information.
