ABSTRACT:
A printing machine is provided, comprising a thin film having first and second surfaces connected by a plurality of hole or recess portions and movably positioned; an ink tank for supplying ink to the hole or recess portions; a thermal head member having a plurality of thermal head elements in contact with the first surface of the film; a driving circuit for selectively driving the thermal head elements; and a recording paper feeding mechanism to feed recording paper adjacent the second surface of the film. The ink fills the holes or recess portions, and the thermal head element is selectively driven by the driving circuit when one thermal head element corresponds to a plurality of holes or recesses of the film, whereby ink is sprouted or jetted from a plurality of the holes or recesses onto the recording paper by bubble pressure caused by heat from the thermal head element. Color printing is also possible with the apparatus of the invention.
