Method of confirming that a pattern to be printed is a high-density pattern and divisionally printing the pattern, and a dot printer which can print high-quality, high-density patterns

摘要

In a dot printer of the present invention, which is capable of printing a high quality, high-density pattern, input pattern data to be printed is stored in an image buffer RAM. A control determination unit checks whether or not the pattern data stored in the image buffer RAM is high-density data by referring to a determination data unit prior to printing, and determines the required number of times of divisional printing in accordance with the checked result. A printer prints the pattern data stored in the image buffer RAM on the basis of the decision of the control determination unit.
