For use when the recordable area of a recording medium is smaller than recording data, there is provided a recording device that can determine the priority of divided areas and preferentially record a high-priority area. The recording device assigns priority to each of the recording areas of a whole image on one page and, if it is determined that the whole image does not fit on the recording medium, performs at least one of rearranging the recording position of a high-priority area, changing the recording size of a low-priority area, and discarding a part of recording data of the low-priority area based on the priority of the recording areas to prevent any part of the image of the high-priority area from being lost.
