Dymo provides the software that allows you to catalogue your labels once created in the event you have a repeat customer. It also allows you to design a variety of styles and shapes to fit your needs. What' great about it is the ability to put your address and logo on the top half and the customer's address on the lower half. It also converts the zip code to a digital bar at bottom of label which allows USPS belt sorters to put in through to zip code stations resulting in faster sorting and delivery. I buy generic labels from a seller in California who gets them from China. Costs a few pennies per label and it also allows you to design a logo for the upper portion.It's the most efficient label printer for shipping padded envelopes.
