This article describes a technique for converting a high quality font to a draft font for use in a serial dot matrix printer. The draft font obtained by this technique is superior in quality to that obtained by a conventional technique to delete every other dot column of a matrix pattern. The convenrsion is conducted by applying the following rules (1) to (4) to each of the rows of each dot matrix pattern as the high quality pattern. (1) If there are four or more consecutive dots, every other dot is to be deleted. (2) If there are three consecutive dots, the first and third ones are to be deleted. (3) If there are two consecutive dots, the second one is to be deleted. (4) If there is a dot without adjacent dots, it is to remain.
