A control device is for controlling a printer. The printer is configured to print by alternatively performing partial printing and sheet conveying. The printer includes a conveyer and a print head. The control device performs: acquiring an object image data representing an object image and additional image data representing an additional image added to the object image, where the additional image has a first length in an area; determining a position of the object image and a position of the additional image in the arrangement area such that the first length of the additional image at the position is minimized, where the first length is greater than or equal to zero.

A control device for controlling a printer includes a conveyer and a print head. The control device performs: acquiring first image data representing a first image and second image data representing a second image; determining, based on the first image, a plurality of head positions of the print head relative to the first image; and determining a relative position of the second image relative to the first image such that, when the number of partial printings for printing the first image and the second image is increased from the number of partial printings for printing the first image, the relative position can minimize the increment.
