For the regular Brother labels, my trick is to fold down the corner a little, that usually makes it easier to peel. You can also cut the whitespace off the end and that sometimes helps. Sorry if this was a double post, but I don't think I saw either of these suggestions in the thread already.

For standard linear tape labels, making a sharp s-curve bend in the label near one end will often cause the backing to readily separate from the label at that end. Brother used to include a nifty little tool for doing just that stuck in the bottom of many of their P-Touch labelers. Don't know
