Printing apparatus which blows ink drops to the surface of the printing paper so that contours formed by the ink drops are letters, numerical figures and other symbols. A time delay is employed in charging the ink drops to be deposited, depending upon whether ink drops are to be successively or non-successively deposited upon the medium upon which printing takes place. By delaying the charging, compensation for the differences in deflection angle due to the pneumatic resistance and Coulomb force repulsion between successive and nonsuccessive dot deposition is effected.
