For a paper feed operation, it is determined whether printing is being performed. When printing is not performed, the paper feed is enabled even in the on-line state, thereby omitting a vain key operation. Further, a line feed key and a paper discharge key are set as the same key and a paper discharge stop function is provided, thereby enabling the line feed of a large amount to be executed by a smaller number of key strokes.
