ABSTRACT:
A printing head drive circuit of a printer is mounted on the side of a carriage having a printing head attached thereto for a allowing said carriage to act as a heat sink. Hereby, no particular cooling means (heat sink, cooling fan and the like) is required for printing head drive elements. In addition, a controller and heat generating parts can be completely separated. Thus, it can be anticipated to reduce the number of parts and the cost required for assembling the whole structure as well as to improve reliability of the printing head drive circuit.
