Abstract: A printing system with a rotatable print drum having rows of raised printing elements disposed about its periphery in arcuate columns, each column having matching bar printing elements positioned at diametrically opposite locations. An impactor assembly cooperates with each column of printing elements for printing indicia on a web advanced between the rotating drum and impactor assembly, the web being pressed against specific printing elements by the impactor assembly. A processor receives coded data signals defining specific bar code indicia and generates command signals for selectively energizing the impactor assembly. Similar bars are printed on the web by pressing the web against alternate ones of the matching bar printing elements for successive coded data signals representing the same bar.

Abstract: A printing system with one drive motor and having at least two printing stations located between a print drum and a plurality of ballistic elements for simultaneously printing at least two document blanks independently advanced through the printing stations by pinch roller and brake assemblies. The printed documents are engaged by an eject roller assembly and discharged through an exit slot after having been severed by a rotary cutter.
