Image supply device, control method of the device, and printing system

An image supply device for supplying image data to a printing device, comprising:

• first setting means for setting first reference information to first image data and second reference information for second image data obtained by executing a predetermined image process for the first image data;
• print control means for instructing printing by transmitting a print job including at least one of the first and second reference information to the printing device;
• reception means for receiving an image request from the printing device in response to the print job;
• image processing means for executing the predetermined image process for the first image data corresponding to the first reference information corresponding to the second reference information to generate the second image data, in a case that the image request contains the second reference information;
• and
• sending means for sending the second image data generated by said image processing means to the printing device.

A control method of an image supply device for supplying image data to a printing device, comprising:

• a setting step of setting first reference information and second reference information to, of images to be supplied to the printing device, images that require a predetermined image process;
• a job issuance step of issuing a print job including reference information of a print target image in accordance with a print instruction using the printing device;
• a first image supply step of supplying, to the printing device, image data which corresponds to the first reference information and has undergone the predetermined image process, in a case that the reference information of an image requested by the printing device in response to the print job issued in said job issuance step is the first reference information;
• and
• a second image supply step of supplying, to the printing device, image data which corresponds to the second reference information and is read out, in a case that the reference information of an image requested by the printing device in response to the print job issued in said job issuance step is the second reference information.
