The printer has a sensor provided upstream a printing head in a paper feed direction to detect whether or not recording paper exists, a device for measuring a paper feed quantity of the recording paper, a central processing unit that controls the measuring device and a printer control circuit, and a comparator that makes a comparison between the measured paper feed quantity and a predetermined value.

Thus, it is possible to prevent the central processing unit from erroneously judging a printed portion of the recording paper to be the trailing end of the recording paper.
