                Order Printers are used by restaurants and bars to print the
                order updates in the kitchen/bar when the waiter updates the order.
              </p><p>
                Each Order Printer has an IP Address that defines the PosBox/Hardware
                Proxy where the printer can be found, and a list of product categories.
                An Order Printer will only print updates for prodcuts belonging to one of
                its categories.
