摘要:
An ink ejecting device includes an ink ejecting member having an ink chamber and a nozzle at a specified position thereof; an ink ejecting driver for reducing the volume of the ink chamber to eject out ink from the ink chamber through the nozzle; and a controller connectable to an image data generator generating image data indicative of a plurality of densities for controlling the ink ejecting driver to regulate the volume reduction of the ink ejecting chamber in accordance with image data. Ink is ejected at an amount corresponding to image data indicative of a density. An image having a gradation can be printed at a high speed accurately and clearly with a simplified construction.
