Some Laser printers have toner that melts at considerably higher Temps. Tech support at Techniks told me this a few years ago. Use the search feature for many discussions on this issue and various paper media. The Brother printers (I had one of the early ones) use high temp toner. The best success I had was printing on catalog paper.
I used an old-type iron to transfer the brother output to PC boards employing a digital turkey thermometer to set the high temp needed (mine has a long flexible lead to the sensor prong.)
For Press and Peel Blue work, I take the ink jet copy to a library or print shot and have them copy it onto the blue sheet. I use the iron preheated to about 325 degrees for these transfers.
