Address Labels Printing
Welcome to SE! There isn't a built in way to print multiple labels for a single contact within the label printing functionality. Demerit's suggestion above is probably what I'd do, but if you have a regular need and want to do it entirely within CiviCRM you could produce a message template with multiple copies of the same address on it and then use the print/Merge Document on the single contact. You would have to be careful how empty address fields were handled to make sure it looked right and the spacing didn't change, but some smarty should be able to do this.
