What he's trying to say is that a thermal inkjet (Canon or HP) heats up the ink and uses steam explosions to shoot it at the paper. This works for dye inks, where the dye is actually disolved in a solvent, so that it's dispersed at the molecular level. If you try to heat pigment inks this way, you cook them into sludge in the print head.

Piezo printers physically push the ink out. Because they don't heat the ink, they can spray almost anything. I've loaded Epson print carts with glue, sugar, starch, nitrogen tri iodide (long story), shelac (yes, real shelac, from bettels), fruit juices, food coloring, gum arabic, Scrip, white paint, etc.

Hope this helps...
