The dot interpolation control system includes a pair of registers for designating initial addresses of interpolated dots along the main scanning direction. Another pair of registers designates a dot pitch along the main scanning direction, and still another pair of registers designates a dot pitch along the subscanning direction. Data pairs of x and y components, which selectively include trigonometric function data representing a designated rotation or inclination angle, are set in the corresponding registers. Dot interpolation of a character pattern is performed by main scanning and subscanning in accordance with the contents of the respective registers.
