Abstract
Ink particles that start flying toward the printing medium P earlier than or later than the ink particles for the line central area are used as ink particles for the line ends. Accordingly, it is possible to compensate for the affects of electrical charges onto the flying path of the ink particles for the line end portions, reducing the amount of bending at the ends of the printed line such that the bend is not noticeable, thereby improving the quality of printing to satisfy consumer demands.
