ABSTRACT:
A processing system to process pattern bitmap data for a printer includes a memory to store pattern bitmap data, a pattern arranging unit to arrange the pattern bitmap data in a size appropriate for a data processing unit in which the pattern bitmap data can be processed at a time, a pattern dividing unit to divide the pattern bitmap data into a first region having a size appropriate for the data processing unit and a second region having a size not appropriate for the data processing unit, and a pattern handler to write/read the pattern bitmap data in/from the memory, wherein the first region is read and written according to the processing unit, and the second region is read and written using one or more units smaller than the data processing unit, such that a processing time of pattern bitmaps is reduced and occurrences of errors (exceptions) in a CPU is prevented.
