Abstract: An interactive ink jet printer prints characters of a language from left to right or right to left in accordance with the direction in which the language is normally written. The signals for the direction in which a motor, which moves ink droplet supply means relative to a recording medium, the signals from a grating, which indicates the direction of motion of the ink droplet supply means and its position relative to a reference position, and the signal for the location of the ink droplet supply means at the reference position are changed whenever the direction of character printing is to be reversed.
