Abstract: In a printing system capable of selectively performing duplex printing and simplex printing, a switching unit switches a sheet travel path between a first path and a second path parallel to each other, and reverses the sides of a sheet that passes along the first path. In the duplex printing, a sheet is printed on a first side by a first printing apparatus, reversed by the switching unit, and printed on a second side reverse of the first side by a second printing apparatus. In the simplex printing, only one side of a sheet is printed by the first printing apparatus and/or second printing apparatus. First and second input units introduce sheets into the first and second paths, respectively; and first and second output units receive printed sheets that have traveled along the first and/or second paths.

Abstract: In a printing system capable of selectively performing duplex printing and simplex printing, a first input unit and a second input unit are adjacent to each other. A first output unit and a second output unit are adjacent to each other. In duplex printing, a sheet supplied from the first input unit is printed on a first side thereof in a first printing apparatus and the traveling direction thereof is changed at a changing unit while the sheet is reversed, and then the sheet is printed on a second side thereof in a second printing apparatus and output to the second output unit. In simplex printing, a sheet supplied from the first or second input unit is printed on one side thereof and the traveling direction thereof is changed at the changing unit, and then the sheet is output to the first or second output unit.

Abstract: A web of paper is printed with selective non-variable information and vastly different variable information on portions of the paper web which are ultimately separated into discrete documents. At least one ion deposition print unit and a number of flexographic print units are utilized, as well as a data source containing at least the variable information, and first and second computers. Data is read from the data source with the first computer and in response to the read data the ion deposition print unit is controlled with the first computer to print variable information on the paper web. Form lag commands are provided from the first computer to the second computer. In response to the lag commands the flexographic print units are independently controlled by the second computer to operatively engage and disengage the paper web and thereby print non-variable information from at least one of the flexographic units on each discrete document portion of the paper web.

Abstract: A multi-pass imaging system and method provides for duplex documents and multiple color images with variable information to be printed by re-entering a substrate into a same tower system, employing a split roller design, for generating subsequent portions of a printed image. When a webbed substrate is fed into a tower, a first one in each of multiple pairs of rollers moves the substrate past a first set of printheads for generating a first portion of the printed image. The substrate is then re-entered into the tower, and a second one in each of the multiple pairs of rollers moves the substrate past a subsequent set of printheads for generating a subsequent portion of the printed image. Each of the multiple pairs of rollers comprise independently operating dual rollers on a single shaft.
