A revolutionary new 'dry ink' for laser printers and photocopy machines

ScienceDaily (Nov. 30, 2011) — Imagine someone inventing a "super-toner," a revolutionary new "dry ink" for copiers and laser printers that produces higher-quality, sharper color images more economically, cutting electricity by up to 30 percent.
