Abstract:
1. A printing control device comprising: an input image data acquiring unit that acquires input image data, the input image data including a plurality of input pixel data, each input pixel data having an input value; a determining unit that determines, for each input pixel data, a difference related value based on a difference between the input value and a threshold value corresponding to the input value; and a generating unit that generates print data by generating, for each input pixel data, output pixel data based on the difference related value, the output pixel data expressing density corresponding to the difference related value, each output pixel data including m blocks, m being an integer greater than one; a first correlation storing unit that stores correlations between a plurality of related values and a plurality of intermediate patterns; and a second correlation storing unit that stores correlations between the plurality of intermediate patterns and a plurality of output patterns, each output pattern indicating which of m blocks are to be turned on, wherein the generating unit comprises: wherein the generating unit generates the print data by generating, for each input pixel data, the output pixel based on the determined output pattern.
