Abstract: A high resolution letter quality 24 by 40 dot matrix ink jet printer includes a movable print head having print elements disposed to print along a slanted line, a character generating module providing character dot patterns to be printed and a modular skewing circuit arranged to receive the dot pattern information and provide the information to the print head in a rearranged order that corresponds to the order in which dot patterns are printed by the print elements. Because the skewing circuit divides each character dot pattern into eight dot pattern modules and operates on the dot pattern modules one at a time in sequence, the finer resolution of a slant head printer can be obtained without need for a huge triangular shift register operating on all of the dot rows of a dot column in parallel to skew the dot pattern information into conformity with the corresponding relative print element locations.
