Print Heads
At this time these printers use printers using PZT crystals as micro-pumps to eject the droplets from the nozzles. The crystals deform to generate a “shock wave” in the fluid inks which in turn ejects a drop from the nozzle. A combination of surface tension, capillary pressure and other complex fluid dynamics ensures that the fluid is refilled ready for the next fire cycle.

Famous quotes containing the words print and/or heads:
“For a long time I was reporter to a journal, of no very wide circulation, whose editor has never yet seen fit to print the bulk of my contributions, and, as is too common with writers, I got only my labor for my pains. However, in this case my pains were their own reward.”
—Henry David Thoreau (1817–1862)
“Though castles topple on their warder’s heads,
Though palaces and pyramids do slope
Their heads to their foundations; though the treasure
Of nature’s germens tumble all together,
Even till destruction sicken—answer me
To what I ask you.”
—William Shakespeare (1564–1616)
