Kind Code:
B2
Abstract:
A printing apparatus can improve the image quality by improving uneven print density or graininess. A printing apparatus is provided with (A) a carry mechanism that carries a medium along a predetermined direction, (B) a nozzle that performs a moving and ejecting operation for ejecting ink toward the medium while moving relatively with respect to the medium during an interval of a carry operation by the carry mechanism, and (C) a signal output section that outputs a first timing defining signal defining a periodical timing for ejecting ink from the nozzle toward a position corresponding to a pixel configuring an image to be printed, and a second timing defining signal defining a periodical timing for ejecting ink from the nozzle toward a position displaced from the position corresponding to a pixel configuring an image to be printed, wherein the signal output section outputs either the first timing defining signal or the second timing defining signal for each moving and ejecting operation.
