I absolutely hate the free Epson and Canon label printing software!
I use DiscLabel at home and at work with Epson and Canon printers and images from Photoshop. It works great, is super easy to use, and their tech support is good. It costs about $40 but I think they offer educational discounts. I have the old version (4) and it does everything I need, I don't know if the new one is any better.
