This is a great idea for a small office and would have eliminated one PC - just doesn't work. If anyone wants it, it will be in the dumpster for the next two days.
Can't think of any - well; it is a great concept
Doesn't really work very well; I attached a parallel HP 2100 Laserjet and an Epson R340 Photo Printer; The setup program is straightforward and seemed easy to use; No errors reported during setup of both printers; The R340 Photo Printer does not work at all.
