Patent abstract
An ink jet printer ejects ink droplets of a plurality of sizes based on image data, and prints dots of a plurality of sizes corresponding to the ink droplets of the plurality of sizes for recording the image. In the ink jet printer, in order to print a smoothing dot close to a normal dot, pulse voltage having a waveform having its printing timing changed from a waveform for printing the normal dot is applied to a piezoelectric element. As a result, an ink jet printer capable of recording high definition images can be provided.
