I've been experimenting with hot transfer of toner onto copper laminate for PCB use and had only moderate success with the method suggested by some, that being the use of magazine paper. I found it messy and somewhat unreliable in practice.
Someone on You Tube advocated the use of 'transfer' paper, the stuff used by laminated sign makers as a peelable backing for plastics transfers. A search on Ebay didn't find that exact product but it produced packets of 'heat transfer toner paper', A4 size. This material is waxy on one side but takes laser print very well. As a bonus, the iron-on result is very good and if done with care, it can be used to make front panels and possibly other lettering on chassis.
I've created a quick video showing my results:

Search Ebay under 'heat transfer toner paper' and quite a few suppliers appear. As I was in no rush at the time, I sent to China (far cheaper than UK!).
