<p>The present invention provides a direct printing apparatus increasing a printing speed and preventing aperture clogging. Each aperture (56) has a size allowing the printing particles (38) for a plurality of dots to pass through it simultaneously. Control electrodes of each aperture (56) comprises a first electrode (68) positioned at the bearing member side and a second electrode (70) positioned at the backing electrode side. The second electrode (70) is divided into a number of parts.</p> |
