Micro$oft Word should have a function to allow you to print to a particular Avery label, or you can download Open Office for free and it definitely has this function.
I agree that for normal bottles you are better off using the little dot labels on the lid so that your bottles are easier to clean and reuse, I only label bottles for swaps or special occasions but heard only recently about using the dots and think it is a great idea.
The search function is up by the top right of the screen, and works best if you use the google option, seems to be much more powerful.
