Amazon .com Automation Software - Print Address Label

I am a seller on [login to view URL] . Until now every time I would receive an order, I would have to look at the order individually, and write down the customers shipping address on the package. This is very time consuming. I need a software that would do the following: As soon as I receive an order on [login to view URL] , it would either 1) Automatically send a signal to my Dymo Label Writer to print a label with my customers address on it or 2) Save the cutomers address into an Excel sheet. This way every day I can print out the Excel sheets onto self adhesive shipping labels, and be able to apply them directly to my packages.
