PURPOSE:To continuously supply figure output for at least one drawing to a printer at high speeds by a method in which an element information is converted into a raster information by an image processor, written in a raster memory by means of an exclusive image bus, and then taken out as dot information. CONSTITUTION:By a host computer interface 1, the element information of figures is taken from a host computer and housed in an element memory 2. By the main CPU3, the whole system including an image processor 4 and a printer controller 5 is controlled. The interface 1, the memory 2, the CPU3, the processor 4, and the controller 5 are connected with a general bus 6. Information read out of the memory 2 is converted in order into raster information by the processor 4 and delineated on the raster memory 7. The information is converted into serial image signal by a video interface 8 and supplied to a laser printer 10. The raster information is supplied to the memory 7 and the interface 8 by the image bus 9. |
