Printing labels

In Contacts, how do I print separate labels on seperate occasions?

I never need a sheet full of labels with the same address. I use labels just a few at a time, so I don't want to have to use a whole sheet each time I need one or a few labels. For example, I needed just two labels from a sheet of 30 -- recepient's address and my (return) address.

There has to be a way to select which label on a sheet gets printed, right? Right??

Thanks.
