Multi-gradation printing was realized by arranging the printheads in multiple layers to form a head, and repeating printing several times using the head. Therefore, there was a drawback that the heating elements were arranged in a matrix, resulting in a complicated pattern. Furthermore, since printing is completed in multiple steps, the head is cooled, resulting in poor efficiency.
