PURPOSE: A printing system, a control method therefor, and a photo-direct printing apparatus are provided to receive and print image data from image supply devices of various vendors by interface-independent image data transfer and printing instruction. CONSTITUTION: If it is detected that the PD printer apparatus(1000) and DSC(3012) have been connected by the cable, these devices can communicate with each other. Applications installed in these devices are executed to start shift to NCDP procedure(701). Reference numeral(702) denotes an NCDP initial state in which whether these devices can execute NCDP is decided. If so, the flow shifts to NCDP procedure(701). If the DSC(3012) does not support NCDP, no NCDP communication control is executed. If the DSC(3012) designates image data transfer/printing by basic procedures after shift to NCDP, as represented by(703), the flow shifts to a simple print mode in which an image file is transferred from the DSC(3012) to the PD printer apparatus(1000) and printed. If the DSC(3012) designates image data transfer/printing by recommended procedures, as represented by(704), various negotiations are done between the DSC(3012) and the PD printer apparatus(1000) to decide print conditions.
