A paper handling apparatus has a simplified structure and allows printed paper to be stacked efficiently. The paper handling apparatus receives printed paper which has undergone printing for each print job and handles the printed paper in an orderly manner. The paper handling apparatus has a stacking section in which printed paper is stacked sequentially for a plurality of jobs and an unloading mechanism for unloading stacked printed paper from the stacking section to the outside. The paper handling apparatus can be used with a printing apparatus which is connected to a large-scale information processing system or similar for printing a large volume of data.

An intermediate buffer device for absorbing the difference in paper feeding speed between first and second printers is disposed therebetween. The first printer prints on a first surface of continuous forms in accordance with the top-surface printing data input from a host apparatus, and the second printer prints on the second surface of continuous forms in accordance with the back-surface printing data input from a host apparatus. A detecting portion detects the amount of retention in the intermediate buffer device. A printer controller stops printing and paper feeding by the second printer when the amount of retention falls below a first set value L1 and stops paper feeding and printing by the first printer when the amount of retention exceeds a second set value L2.
