ABSTRACT:
An accumulated-heat correction apparatus for a thermal head, wherein print data of each line are outputted to the thermal head, and a conduction time of the thermal head is controlled on the basis of the print data, includes cumulative-data calculation means for calculating cumulative data which is ascribable to accumulated heat of the thermal head up to a previous line (n−1), next-line data calculation means for calculating print data of a next line (n+1), correction-data generation means for calculating correction data (ΔTs) which corrects print data of a current line n, by using the cumulative data and the next-line data, and head control means for controlling the conduction time of the thermal head on the basis of the correction data (ΔTs) which has been generated by the correction-data generation means.
