Sorry, I didn't see your posts until now. Yes you do need a laminator to make this work, The one that Pulsar recommends works great and is well priced.
Essentially the process is this:
1) Lay out your artwork and print it out using a laser printer onto specialized sugar coated paper. This paper looks just like the green colored decal paper that came with plastic model kits. In the case of the Gorf panel I needed a color laser printer because I wanted full color.
2) Drive all of the water out of the transfer paper with a heat gun. Apparently all papers must have some moisture content to me able to run through a laser printer without jambing.
3) Run the specialized paper through the laminator with a specialized toner transfer material that sticks only to the toner. If there is any moisture in the paper the transfer material will stick to it also which is why you do step 2. If you want a single color transfer then you print the original normally, if you want full color you need to mirror the image because the transfer material goes under the toner not over as in single color.
4) Use low tack masking tape to pull off any extra transfer material from the paper that stuck in areas that don't have toner under it
5) Run the paper through the laminator with a sheet of clear mylar over it. The transfer material will stick to the mylar via a static charge.
6) Submerge the paper and mylar into a water bath. The water dissolves the sugar on the paper and releases the transfer material so it is now stuck onto the mylar.
7) Spray alcohol based adhesive onto the toner material and mylar.

Place the mylar/material over the landing spot and press the transfer into place. The bonding between the adhesive is stronger than the electrostatic charge so it will release from the mylar and stick to the surface.
This process seems complex, and it is, but the results are stunning! This lets you do things that you can't do any other way without very expensive industrial equipment.
