The past print data of plural heating resistance elements adjacently disposed are stored and latched in first latching circuit, the present print data is stored and latched in second latching circuit, and corresponding to the latched outputs of these first and second latching circuits, when the heating resistance elements have printed in the past and when the heating resistance elements adjacently to both sides of each heating resistance element are presently used in printing, it is controlled so as to shorten the driving time. As a result, blurring of the print due to excessive temperature rise of the heating resistance elements may be suppressed. Hence, the printing quality may be enhanced.
