PROBLEM TO BE SOLVED: To transfer plot data at high speed from a plot memory to an image output apparatus. SOLUTION: In order to transfer plot data in units of N (e.g. four) raster lines to an image output apparatus, N plot memories 3-1 to 3-N are provided. An (i) intermediate code (i=1-N) of intermediate codes of N lines input to development parts 2-1 to 2-N is developed to an (i) plot memory among the N plot memories 3-1 to 3-N. When the plot data of at least one line is stored in each of the plot memories 3-1 to 3-N, the plot data is transferred in parallel to the image output apparatus. |
