摘要： A color printing apparatus includes a printer driver for receiving a print instruction of print data issued from an application program, and for rasterizing the print data to produce con-tone/multi-bits bitmap data and bi-tone/single-bit bitmap data; a page memory for independently storing thereinto both the con-tone/multi-bits bitmap data and the bi-tone/single-bit bitmap data; a control unit for executing a control operation in such a manner that the con-tone/multi-bits bitmap data is converted into con-tone/multi-bits print data, the bi-tone/single-bit bitmap data is converted into bi-tone/single-bit print data, and at least one of the con-tone/multi-bits print data-and the bi-tone/single-bit print data is stored into the page memory in a bitmap format; and an output control unit for reading at least any one of the con-tone/multi-bits print data and the bi-tone/single-bit print data from the page memory, and for logically synthesizing the print data with each other to output the synthesized print data to a color printing unit, reducing the data amount of the bitmap data.

摘要： A printing control system includes a drawing unit, a block data generating unit and a controlling unit. The drawing unit sets a drawing region in which a region of an original image falls, and draws the original image in the drawing region so that a center of the region of the original image is in coincidence with a center of the drawing region. The block data generating unit divides the drawing region into a plurality of blocks, each block having a size and shape identical to one another, and generates block data representative of the plurality of blocks. The controlling unit performs an image processing on a block data basis to generate print data. The image processing includes a rotating processing for rotating each block.

摘要： A halftoning device that converts an input pixel signal of 8 bits per pixel into an output pixel signal of r bits per pixel(r 8); a threshold value array storage that stores a threshold value array having a threshold value of 8 bits; and a threshold value expansion unit that expands the threshold value of 8 bits to expanded threshold value of n bits per pixel. A range of the expanded pixel signal output from the gradation correction unit is matched with a range of the expanded threshold value. The output pixel signal is set according to a comparison of the expanded pixel signal with the expanded threshold value corresponding to the threshold value that is selected for each input pixel signal.
