Homebrew PCBs

Just running this over in my head and wondering what pitfalls there would
be.  As you probably know, there are a couple of commercial laser printers
out that that have white toner available.  OKIData sells one.  Unfortunately
as the classification implies, commercial means $$$ and those printers are
$3000+.  But I'm wondering, given that you can buy the white toner powder
online (I've checked).. what's to stop you from simply refilling a spent
black toner cart with white, and then doing your transfers for silkscreen
with that?  Would the printer care?  

 

Obviously you'd have to match the 'type' of toner to a printer that uses the
same type.  Maybe even just get a second hand mono OkiData for cheap.  

 

I'm thinking if this could work, you wouldn't even have to do anything
special to your silkscreen artwork.. you just print it 'as black' and it
comes out white.  


But I'm sure it's not this easy.  

 

Thoughts?
