PROBLEM TO BE SOLVED: To reduce a memory capacity of an expanded image data by changing a readout order of a compressed image data on a memory according to the rotation direction of the image and rotating the expanded image data. SOLUTION: Image blocks arranged in order are called in such an order as being commanded by a readout instruction means 9 so as to be printed in the rotational direction commanded by a computer. The called image block data is a compressed image data so as to be expanded by an expanding means 10, while timing with a printer 7. This image data is rotated by a rotation means 11. After the numbers of vertical and lateral pixels are conformed in the rotation means 11, the image date is stored temporarily in a memory 12. Because the image is rotated according to the signals from the image source such as the computer, the readout order the image data in the block is instructed and the image data is read out in a prescribed order so that the rotated image data can be provided. |
