Has anyone tried it?
"Liquid Gel is a remarkable alternative to traditional colour laser and ink jet printing. The viscous ink is a fast drying, water resistant formula that reduces blurs and bleeding while producing laser-like quality prints on plain or recycled paper."

Seems pretty promising to me, it uses cartridges like inkjet printers, so the modification should be easy! I could get a used Ricoh GX 3000 for about 100USD in my country.
