We know you have a choice when you buy scales online. Just know that when you buy digital scales from Old Will, it's always a "Worry Free Deal".
Use this adapter along with the Ohaus 71147376 RS232 Interface Kit for Scout Pros or 83032107 Interface Kit for the Navigators to connect your Ohaus scale to the Ohaus Dot Matrix Impact Printer. You'll need to purchase this adapter, as well as the RS232 kit, for your scale because it is not included with the 80252042 printer.
