Is there any way to print white colour onto paper?
There is white Trace-it transfer paper from a company called ScratchArt[1]. This would require you to print out your image first then trace over image to make the actual image transfer.

Similar to the idea of carbon paper instead in this case the paper is coated on one side with lose layer of white ink bound with wax. The image is transferred by placing the coated side down gently onto a surface and then scribing the image on the non coated surface.
