An image processing apparatus is connected to a print control device that controls a single printer, the apparatus includes a first generating unit that generates a first corrected image by adding an adjustment image to one of edges in the first direction of the first image such that a length in the first direction is equal to an integral multiple of a predetermined boundary size, a second generating unit that generates a second corrected image by adding the adjustment image to at least one of both edges in the first direction of the second image such that the length in the first direction is equal to an integer multiple of the boundary size, and a transmission unit that transmits the first corrected image and the second corrected image to the print control device.
