PURPOSE: To reduce a running cost of a laser printer system by injecting to fly ink of an emitted part with a laser beam by expanding or vaporizing, and adhering the ink to a printing medium disposed near an overall surface of an ink holding medium to print it. CONSTITUTION: The laser printer system comprises an ink holder 2 of a thin lengthy shape disposed near a printing medium 1 such as paper along an X direction, and an antireflection film 6 transparent for a laser beam and provided on a back surface of the holder 2 to inhibit passage of ink. With such a constitution, a light guide passage 10 and light guide plate 5 are formed of material of transparent quality for the laser beam 11, and a refractive index of the passage 10 is selected larger than that of the plate 5. Accordingly, the beam 11 is transmitted and output to a light guide outlet with low loss. And, the ink immersed into the ink holding medium 2 through the film 6 and held in the medium 2 is heated, expanded to be injected, and the ink is adhered to the medium 1 to be printed. |
