An electronic apparatus such as an electronic typewriter includes a display device and has a plurality of modes of operation selectable by an operator. The operation mode selected by the operator is displayed on the display device that can also display character data input to the apparatus by an input device such as a keyboard. The display device displays the selected mode after displayed character data is printed in response to the operation, for example, of a carriage return key when a line-by-line printing mode is selected or a space key when a word-by-word printing mode is selected.
