Abstract

PURPOSE: To minimize the thermal accumulation of a printing head and make print density uniform by controlling head energizing energy based on the second dot of data before the dot of print data for which the head is to be energized when dots of the same data are used.
CONSTITUTION: Given data for which a printing head is energized, that is, the one two dots or one dot before data at the position of a dot, as D-2, D-1, CPU 1a temporarily holds the data in RAM 1b. Next given data located at a position for which the head is energized as D0, CPU energizes the head for the pulse width(a) part in accordance with the result obtained by performing the 'and' operation on data complement of data D-2 two dots before the dot for which the head is energized and data D-0 for which the head is to be energized now. In addition, the CPU switches the head ON for the pulse width (b) part in accordance with the results obtained by performing the 'and' operation on data complement of data D-1 one dot before the dot and data D-0 for which the head is switched ON. Finally the CPU switches the head ON for the pulse width (c) part in accordance with data D-0 for which the head is to be energized. Thus these four-step pulse widths can be controlled using the printing head, and therefore, the effect of thermal accumulation on the head can be minimized.
