MIke N., see this video showing the use of this medium:
Toner transfer video using Oracal 651 vinyl:
https://www.youtube.com/watch?v=FtmJdCBjwXYI got the drayer and will have another go at TT with this medium. The Oracal 651 comes stuck to a paper backing. The paper backing peels off. The vinyl then has a sticky side which you can attach to piece of paper and feed through the laser printer. I figured out how to do this using EAGLECAD and made a template so I now know exactly where to attach the sticky vinyl to the paper just before printing it. If the vinyl gives me any trouble, I'll try printing the artwork onto the glossy paper backing before I consider another medium.
