Can't post a one star review because somehow it wont let me. But don't waste your time. Wasted about two weeks trying to make this app work. There is no support. Get an app that has support instead. It works initially, and it can print labels with the dymo app, but then the barcodes cannot be recognized by the socket scanner, which makes it all worthless, because if barcodes cannot be read, there is no point in using them.
