This junction box allows you to fix two parallel printers to one computer and switch between them when printing. One lead runs from the parallel port in the computer to the junction box, and two leads run from the junction box to the printers. The switch on the front of the junction box allows you to choose which of the printers you wish to print to at any time, thus negating the need to remove wires from each printer. This box does NOT work with USB printers, only with the older parallel type. All three leads are supplied.
Collection only, I am in Newark.
