An ink jet printer includes an image control unit that controls rotation of image data so that a direction of a short side of a rectangular area in a printing sheet becomes a print width direction that is orthogonal to a sheet transport direction if a first warm-up time calculated by a warm-up time calculation unit is shorter than a warm-up time until an ink temperature of an overall ink discharge target width of an ink jet head reaches an appropriate temperature range. |
