ABSTRACT:
A printing apparatus of the type capable of printing on both sides of a paper supplied thereto is improved by enabling simple operation through the use of a single operating lever. Adjustment devices allow simple vertical and transversely adjustment of the plate cylinders with respect to the paper position. After printing is effected, the operating lever is shifted stepwise from the printing position to a starting position through intermediate positions wherein blanket cleaning and plate ejection functions are effected. Changeover between single and two-sided printing is easily effected by a simple switch operation.
