Abstract
A method and system for printing a high density sequence of characters of M characters per inch from a predetermined character set. A print head having multiple print wires or pins is utilized to print a matrix of 'dots' at a selected pel density, preferably 4M pels per inch for higher print throughput. The character set is then examined and a small selected number of characters are identified which require a character matrix having a width of four pels to achieve a desired level of legibility. All remaining characters in a character set are assigned a character matrix having a width of three or three and one-half pels in order to achieve the desired level of legibility. Thereafter, a high density sequence of characters having a high level of legibility can be printed at low pel densities having only a slight degradation in legibility in the event that two characters which each require a four pel width character matrix are adjacent.
