Abstract: An electronic typewriter capable of being changed over in operating mode selectively between a non-print mode and a print mode, during text creating operation, for storing entered data in a text memory. An objective position, to which the print head is to be moved, is decided through calculation when operation mode is changed over again from non-print mode to print mode, after the operating mode has previously been changed from print mode to non-print mode. When the print head is moved toward the right margin on the basis of the calculated result, sheet feed operation is not executed, whereas, when the print head is moved toward the left margin on the basis of the calculated result, the sheet feed operation is executed prior to movement of the print head. Thus, duplicate printing on the recording paper is advantageously avoided.
