ABSTRACT:
A matrix printer normally cooperates with a particular character generator by means of which coded information representing characters to be printed is translated into a matrix of print commands for print styli printing dots out of which a character is composed. In accordance with the invention, the same character generator is used for printing smaller characters in superscript, subscript or in formal footnotes, by using a particular algorithm to translate the generator information into different set of information for each character, so as to reassign print commands for the several print styli.
