A method and apparatus for printing multiple lines of characters simultaneously on a dot matrix printer and making available to the user a choice of alternate line spacings without physical or mechanical alteration of the printhead. The printhead includes an uninterrupted array of print elements having a total height greater than the combined total height of the multiple lines that are simultaneously printed plus the combined height of the intervening line spaces. By directing columnar character data to selected sets of print elements, the printhead can produce characters of a constant height with selected variations in interline spacing.
