Abstract: This disclosure deals with a machine for printing indicia on a moving web. The web may consist of a long relatively narrow carrier strip having rows of tax stamps or decals formed thereon, and the machine prints indicia in the form of code symbols on each stamp. The stamps are arranged on the carrier strip in rows which extend longitudinally or in the direction of the length of the strip, and the strip is moved longitudinally through the machine during the printing operation. In the described example of the invention, a plurality of such rows are provided, the rows being laterally spaced across the width of the web, and the laterally adjacent stamps are arranged in laterally extending straight lines. The machine prints a group of symbols on each stamp, and the symbols are the same for every stamp on a given length of the web.
