Abstract

When a recording density is set to more than 600 by 600 dpi in a hot melt printer, a recording image with excellent quality is obtained when a recording condition is determined to a specific range. For example, a quantity of an ink droplet ejected by the ink jet head is determined so that an ink clinging amount on a unit area of the recording paper is in a range from 7.2 × 106 to 2.1 × 107 pl/inch2 when the dots are printed in an overall area of the unit area. This range varies when a pair of pressure rollers are provided for applying a pressure to the recording paper on which the dots are printed. This range also varies when a plate-shaped heating element is provided for heating the printed surface of the recording paper.
