Splasm Software (http://www.splasm.com/returnlabels/) has released Return Labels, software for creating return address labels on your Mac. Features include rich text editing tools, built-in images, and the ability to import a contact from your Mac’s Contacts or Address Book.
You can use any font of any style with Return Labels. The size, style, line spacing, and color are up to you.
You can choose from a collection of images and pick accent and background colors for many of them. You can drag and drop any photo or image to add a personal touch to your labels.
There’s no limit to how many labels you can make. Return Labels saves them so you can print them again any time. The app is available on the Mac App Store for US$4.99.
