ABSTRACT:
An object of this invention is to present a thermal printer for printing at high speed the data with the drive at a low voltage of around 5 V while preventing the printing problems attributable to the voltage drop due to internal impedance and to the loss inside the head coming from the common conductor inside the head. The thermal printer has a plurality of heating elements.
The thermal printer comprises a print head consisting of the print blocks which have divided the heating elements at every stipulated quantity and a heating means for electrically heating the heating elements on the basis of the stipulated data at every print block wherein the heating means has been structured to simultaneously heat the heating elements against a plurality of print blocks to color the thermosensitive paper in contact with the heating elements of the print block.
