INK JET PRINTER, AND DRIVING WAVEFORM GENERATOR AND GENERATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an ink jet printer and a driving waveform generator and a generating method of an ink head in which high accuracy printing can be ensured even if a noise pulse enters a reset signal or a floor signal. SOLUTION: A driving waveform generating circuit 46 generates a waveform for driving a plurality of drive elements in an ink head 50 and performs logical operation of a flag referring to an operation mode signal, a reset signal and a floor signal such that the reset signal and the floor signal do not become active when a noise is mixed thus preventing disturbance and deterioration of image quality and damage of the head.
