Here is a site that sells tiny fonts for quilt labels:

Be aware that although they advertise this as a 'font' they are really collections of letter designs. You can't type words, you will need to place each letter design to make your words. You may be able to do it on your machine, or may need a program like Embird. Once you take the time to create the first label, you can reuse it, keeping the info that hasn't changed.
