<p>A printer which allows a hyphen preceding or succeeding a word to be erased or not to be erased when words are erased on a word basis, and also relates to a printer which allows only a hyphen to be erased. Although, up to this time, a printer equipped with a mechanism to automatically erase words on a word basis has been available, there is a problem that even when only one word containing misprinted letters out of two words connected by a hyphen is to be erased, both of said words and the hyphen are erased, resulting in an unnecessary erasing and printing of a correct word to decrease work efficiency. In view of the above, to solve the problem described above, this invention provides a detecting means which detects, upon receipt of a command for erasing a word, whether there is a hyphen or not at a print position one letter ahead of the leading letter of a word corresponding to a print head or at a print position one letter behind the trailing letter thereof, and provides a control means which causes said hyphen to be erased on a signal from said detecting means or a control means which keeps said hyphen from being erased; or provides a control means which controls the operation of a mechanism for erasing according to a signal from the detecting means.</p> |
