you will not be able to print onto plastic stickers unless you have a leserjet printer, its better worth your money to find a local sticker printer than to buty sticker paper, trust me ive looked into it, a small business will do it for about 20 cents a sticker
but if you think about it a professionally made sticker on a 50000 dollar printer for 20 cents is going to be much more.. "sellable" then a homemade self cut sticker
