Abstract
To provide a thermal line printer and a method of driving the thermal line printer, which may suppress the degradation in printing quality such as non-uniformity in density caused by the sticking phenomenon. A method of driving a thermal line printer for performing thermal recording onto thermal paper to be fed by a drive of a stepping motor with a thermal line head where a plurality of heating resistors are arranged in a linear manner on a line perpendicular to a paper feeding direction, includes the following steps of: dividing the thermal resistors of the thermal line head into n blocks (where n is an integer not smaller than one), and further constituting m groups (where m is an integer not smaller than zero) by the n blocks; and driving each of the groups in order, and driving the stepping motor after each drive to thereby perform a paper feed less than one dot.
