Abstract
A non-impact printing apparatus in which an ink carrier film is formed to have a plurality of holes or recesses, the holes are filled with ink, and then the film filled at the holes with the ink is selectively heated by a thermal printing head according to image information to generate bubbles within the ink in the heated holes and thus to eject the ink onto a printing paper under influence of the pressure of the generated bubbles. The effective diameter of each of hole provided on the ink carrier film is less than the thickness thereof thus improving the image quality.
