Abstract

A method for driving printing elements of a dot matrix printer provides that the matrix dots to be printed are to be thinned out without any thin lines, in particular steeply inclined thin lines, being lost. To this end, the columns of the matrix are considered to be arranged next to each other in pairs, and before the matrix dots in each line (Z) of the matrix are thinned out, a matrix dot is placed before or after a matrix dot used initially to create the character, so that both matrix dots belonging to a pair of columns (SP1, SP5) are covered by a line (Z). During the subsequent thinning out, the lines are printed sufficiently well and clearly. The process is intended for use in dot matrix printers.
