A method and associated apparatus for printing font character bars comprised of a plurality of rows which are in turn comprised of a plurality of close adjacent dots to improve print quality and readability thereof by optical reading apparatus while increasing potential print speeds. The basic method comprises removing a portion of one dot or more from an end of each of the plurality of rows of a character bar which is too wide for optimal reading by optical reading apparatus. Alternative methods and apparatus for automatically adjusting the fonts and printing temperature of a thermal printhead as a function of system parameters are also disclosed.
