I spent a long time figuring out why it wasn't working right. If you have problems with it not working at all, use the customer support at Dymo and search for USB or however you connected. It will then give instructions on how to reload the drivers which worked great. Also, make sure your label roll is TIGHT on the spool. Mine was a little loose and that really fouled it up. Now that I have it set up right it is great. You can add graphics and such to your labels. The labels also come in other colors.
