There is something in the toner that while not liquid, is certainly 
thermalplastic, and that generally involves something that could be volatile, 
maybe even explosive at high temps.  Toner recipes of course are guarded by 
armed guards and pit bulls 24/7 as that is the 'magic twanger' that makes it 
all work.  Most printer folks would have no problem killing those who would 
try to obtain that very proprietary info without being part of the crew that 
actually mixes it.  It is all a very cloak and dagger business.
