An image processing apparatus that can be connected to a printer includes: an image data storage unit that stores image data of a first data format which can be printed by the printer and image data of a second data format which cannot be printed by the printer; a print image designating unit that allows a user to designate image data to be printed from the image data storage unit; a print job generating unit that generates image data identification information corresponding to the designated image data and generates a print job including the image data identification information; and a print job transmitting unit that transmits the print job generated by the print job generating unit to the printer. When the designated image data is the image data of the second data format, the print job generating unit generates the image data identification information and generates the print job, without converting the second format into the first format.
