I think you can make labels that look really nice, but you really can't compare your home laser printer to a professional print or label houses digital prints. There are a couple of label company sponsors on this site you could use. You can also find a local printer to print out your design for you. You've got to remember you've got a 2 or 3 hundred dollar printer and they have 200 or $300,000 printer to work with. You also have to start with professional looking designs and high resolution quality artwork in order to end up with a professional looking label.
Best of Luck, there are a lot of people on this site making some really nice and also unique labels at home.
