Abstract
When a number of exothermic elements arranged linearly are used for printing, driving data are inputted to the gate circuits of each exothermic element, and the gate circuits are controlled by the strobe signals in the conducting/nonconducting state. The circuit gates are divided into groups and the strobe signals different for each group are inputted in sequence. At printing, when there is the group having a relatively small number or no exothermic elements being heated and driven, and the strobe signal is given to each group successively for any groups, the necessary driving time may be wasted. The operating speed many be improved if a plurality of strobe signals are outputted in parallel when the number of exothermic elements being heated and driven is relatively small, and if the corresponding strobe signals are stopped when there is no exothermic element, and outputting the next strobe signals immediately in both cases.
