Lee I have a ThinkJet printer (thanks for the printer driver in 1.3!!) with the same type of disposable print head. The head works by applying current through a resistor next to a tiny ink chamber. This heats the ink until it vaporizes, forcing the ink in the nozzle to squirt to the page. HP went to great lengths (as described in one of their journals) to create an ink with just the right properties (viscosity, surface tension, condensation to liquid when the vapor bubble cools, etc.) It seems unlikely that an off the shelf ink would be very sucessful here. Of course, the Paintjet printer might work in an entirely different manner, but red, green and blue (and brown) inks are now available for the Thinkjet (sounds suspicious to me :-) :-)). | // You've heard of CATS and DOGS, I'm from GOATS, Dave Kinzer | | // Gladly Offering All Their Support! noao!nud!fbog!dbk | | \X/ "My employer's machine, my opinion."
