Printing system, print control method therefor, and photo-direct printing apparatus

摘要

In transmitting image data from a digital camera (DSC) to a PD printer and printing the image data, the PD printer transmits its Capability to the DSC at once after communication procedures by an application (NCDP) installed in the PD printer and DSC are established. If Capability contains an item which cannot be understood by the DSC, the DSC ignores the item. Also, if a print job from the DSC cannot be executed in the PD printer, priority is given to the function of the PD printer to print data.
