Welcome to the discussions, Ed.
If you print a label from an Address Book contact you will get one label, not a sheet of labels. If you use Address Book to print contact addresses directly on to envelopes you can get it to print a return address also.
There is a product
Roll Call Directory which will do this, but it has not been updated for a couple of years, so I don't know how usable it still is. Maybe you could try it and let us know 🙂
