An image processing apparatus that allows accumulated image data and print control data to be transferred to another image processing apparatus and that may improve user convenience. The image processing apparatus is communicatively connected to another image processing apparatus. A storage unit stores input image data in a first format. A reception unit receives from the another image processing apparatus information indicating a format of image data capable of being analyzed by the another image processing apparatus. An identification unit identifies, based on the information received by the reception unit, software for converting the image data from the first format to another format of image data capable of being analyzed by the another image processing apparatus. A transmission unit transmits the image data stored in the storage unit and the software identified at the identification unit and information indicating a location where the image data is stored in said storage unit to the another image processing apparatus.
