ABSTRACT:
A character erasable printing apparatus is designed to erase a character or an underline in plural times of erasing action by moving the printing head, and to print a character by a single printing action.
Therefore, when an underlined character is erased together with its underline, and a correct character is printed together with an underline, the underline is interrupted.
Disclosed are, to pervent such interruption of the underline, a character erasable printing apparatus capable of erasing only the character without erasing the underline when the underline mode is being set, a character erasable printing apparatus capable of erasing only the character without erasing the underline when erasing a character adjacent to an underlined character, and a character erasable printing apparatus capable of erasing the underline without moving the printing head when erasing an underline of a character adjacent to an underlined character.
