PROBLEM TO BE SOLVED: To obtain an image processing unit that can process image drawing, characters and graphics altogether at a high-speed. SOLUTION: A CPU 5 interprets an image-drawing instruction, and receives data and only stores the data to a memory 4 and leaves the succeeding processings to an image-drawing processing unit 6, when the received instruction is the image drawing instruction. When the received instruction is the character graphic drawing instruction, the CPU 5 generates a bit image that is paint-out range information, stores the image to the memory 4 with color information and leaves the succeeding processing to a graphic image drawing processing unit 2. As a result, the load on the CPU 5 is relieved and intermediate codes given to the graphics drawing processing unit consist of the bit image and the color information and an overhead can be reduced, even in the case of painting out a small area and high-speed processing is attained in a printer.
