When printing of the job A is terminated and conveying of roll paper is stopped, a job B is started and conveying of the roll paper is started and the printing for the job B is executed, waste paper information 72 for the waste paper between jobs is printed on the final page of the waste paper which is the page before the first page for the job B. Then, printing for the job B is started and when the waste paper occurs before printing for the job B is terminated, waste paper information 73 for the waste paper in the job is printed on the final page of the occurred waste paper.
