ABSTRACT:
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.
