Abstract
A printing system for a dot printer for printing matrix patterns in the form of aggregated dots which consist of orthogonal rows and columns, has a first memory having first and second memory areas for storing pattern data corresponding to the rows and columns of the dot matrix patterns. The data corresponding to successive columns of each one of the dot matrix patterns are stored in the first memory area and numerical data specifying a total number of times each respective successive column is to be repeated in the respective pattern are stored in the second memory area. A second memory temporarily stores the dot matrix patterns specified by the pattern data and a control means causes the dot matrix patterns to be generated in the second memory in accordance with the pattern data stored in the first memory. Thus, when two adjacent successive columns are identical, the first memory need only once store data corresponding thereto so as to thereby reduce the amount of memory area needed for storing a dot matrix pattern having repeated identical successive columns.
