Copier Toner uses?

Try using weathering powders, pastels or other effects instead, much more pleasant!

I work with printers every day, It's basicaly rust bound to black powder, gets where you don't want it, it's a health hazard, & a SOB to clean up. etc, etc....

I've used it to print copies, (duh!) such as drawing templates to stick to plastic & cut out.

 Also to print reversed images out, then use meths or similar to 'print' the reversed image onto stuff like wood that you can't photocopy onto, but that was many years (decades) ago when I was an art student.... Happy, Single & Skint!

Ya, it'd be quite usable, but I wouldn't mess with it... Just soooo easy to spill that crap and God help ya if ya get it where ya don't want it...

I'd favor using lampblack  (the soot you can collect from a burning candle, burning oil lamp, or burning styrene) over that stuff...

Having had many opportunities to do battle with recalcitrant toner cartridges, I would think that it would work, as it sticks like certain substances to blankets. It is a known carcinogen (like many of the products we use), and can be difficult to get off areas you don't want it. Might be more trouble than it's worth, but with care its doable.
