ABSTRACT:
Laser printers are provided parallel one another so that their respective control panels face one another to define a single work station. Paper web travels from an unwind machine through the first laser printer, and instead of being provided directly to a rewind roll or the like, the paper web is adapted to move around turning bars associated with the output end of the laser printer and the input end of a second laser printer. The turning bars are oriented parallel to one another and a reversing roller results in travel of the paper web, in an upside down fashion, to a second laser printer so that it can be printed on one side in the first laser printer and on the opposite side in the second laser printer. The laser printers are also capable of printing on two individual paper webs with individual unwind and rewind machines associated with the opposite ends of the two laser printers thereby providing for conventional operation of the laser printers in an alternative mode of operation. Even so, the advantage of providing a single work station between the laser printers still exists. The laser printers are electrically interfaced with one another so that printing on the opposite sides of the web can be coordinated.
