Black and white prints from a laser copy machine can be transfered to wood using acetone. Do a mirror image print, tape it face down, soak with acetone using a rag and rub it with a spoon or other tool. Works much better and easier than trying to use an iron to transfer the print.
Art supply stores that sell magic markers for artists will have a colorless blender which artist's use to blend colors. It has a felt tip nib which makes it a good rubbing tool and obviously contains acetone because it works exactly the same.
The paper used in color copy machines is too thick to get a good image transferred. The copy place near me won't run ordinary black and white laser paper through their color copier. I'll have to look around and see if I can find a plce that will. Will let you know.
