There's a Hero on Your Desktop - Popular Science

To most, it's just a printer. But to tissue engineers, rocket scientists and architects, the good old inkjet is the secret to grand innovation
If you were to toast the most dazzling gadget in your home, you might compose an ode to your plasma TV, recite a limerick about your computer-controlled telescope, or maybe sing the praises of your video conferencing, nose-hair-trimming espresso maker. But the invention most deserving of your adoration, the contraption that will one day sit in the pantheon of great American machines alongside the telephone and the transistor radio, is something far more prosaic. It is the inkjet printer, and it is much more than a peripheral. Its core technology may seem simple—an array of nozzles that moves back and forth, depositing tiny droplets of ink on paper—but its breadth of uses has turned out to be nothing short of astonishing, so much so that the humble inkjet is driving innovation in disciplines from aerospace engineering to pharmacology.
So starts this rather interesting article on inkjet printers and the technology behind them. Quite interesting. Who knew that the inkjet would be the forefather of the famed Star Trek replicator.
