US Patent 7773244 Print apparatus, control method thereof, and print system

A sensed image is saved in a printer in an environment in which a digital camera can directly communicate with a printer, and the sensed image can be directly printed. A printer and a digital camera (DSC) can be directly connected to each other via a USB interface. Upon this direct connection, the digital camera and printer serve as a print system, and the DSC serves as a user interface in that system. When the user inputs a print instruction of a desired image on the DSC, a print process of that image is executed. When the user inputs a save instruction of a given image, that image is saved in a storage device in the printer. Even when the image is erased on the DSC side, original image data can be prevented from being lost.
