first class us mail shipping labels

[Twister]

Hi all,

We sell small, very light weight products and for most customers first class US mail is the best shipping option since we mostly ship in 6x4x3.5 inch cartons.
Does anyone know of a contrib or add-on that would allow us to automatically print a mailing label with our logo, return address and the customers shipping address when an order's status is changed to "shipped"?

Would be a real time saver!
