This unique printer applicator allows one machine to do the work of three. As a pallet approaches the printer applicator a tamp assembly, with a label on the tamp pad, is extended. Once the tamp assembly is fully extended, the tamp pad rotates towards the approaching pallet and applies the label to the front panel. The tamp assembly then retracts to home position. As the pallet passes by the printer applicator, the tamp module extends just far enough to apply a label to the side panel. Once the pallet has passed the tamp module, the entire assembly extends again. This time the tamp pad rotates towards the back panel and applies a label. For added flexibility, operators can select label application to one, two or three panels of pallets or cases.a
