Abstract

PURPOSE:To conduct printing with the high accuracy of quality by moving a printing head or a carriage, on which the printing head is loaded, at a minute distance in the vertical direction and conducting printing when printing at high density is conducted by two passes or more. CONSTITUTION:A carriage 4 on which a printing head 3 is loaded is kept under a horizontal state while facing a printing surface in a platen 1 on which a sheet of paper P is wound, and characters are printed. A shaft 5a is lifted only by a minute distance by turning a minute feeding mechanism, an eccentric roller 6, thus integrally positioning the printing head 3 to the carriage 4. The sheet of paper P wound on the platen 1 is printed as it is left as it is brought to a fixed state by operating the printing head 3.
