Abstract
Abstract Data entered from a keyboard of a typewriter is stored in a text memory, and then, the data stored in the text memory is read out and printed on a paper. In order to fully print the data stored in the text memory, a first printing control means is operated. In order to stop the printing operation at a position which was not intended when the text was created, the printing operation is stopped by a second printing control means every time one line is printed.
