Abstract:
An electro-coagulation printer which comprises a rotation drum adapted to hold a conductive ink film on its surface, a plurality of electrodes configured to when electrifying partially coagulate the conductive ink film to form ink dots on the surface of the rotation drum and a transfer section for transferring the ink dots onto a paper, said electro-coagulation printer comprising:an interface for receiving print data from an external device; a data processing section for creating gradation data corresponding to a collection of gradation values designating gradations for pixels on the basis of the print data; an output timing control section for controlling output timings of one line of the gradation values with respect to the electrodes respectively; a pulse generation section for receiving the gradation values whose output timings are controlled by the output timing control section and for generating pulse signals in response to the gradation values respectively; and an electrode drive section for driving the electrodes in parallel in response to the pulse signals respectively.
