On October 22, 1938, when American inventor Chester Carlson together with German immigrant Otto Kornei first transferred an image from a glass microscope slide to a sheet of wax paper using method later called electrophotography. Kornei wrote the words “10.-22.-38 ASTORIA.” in ink on a glass microscope slide. Then the experimentalists prepared a zinc plate with a sulphur coating, darkened the room, rubbed the sulphur surface with a handkerchief to apply an electrostatic charge. After that they laid the slide on the zinc plate, exposing it to a bright, incandescent light.

The technology makes it possible to manipulate particles smaller than 100 nanometers, which delivers resolution equivalent to 100,000 dots per inch. Compare that to maximum resolution of 1,500 dots per inch of current offset printers.

Inkjet technology has a bright future, as people are looking for alternatives to laser. The introduction of Memjet and Edgeline is another proof of that. It is just going to take time for page-width inkjets to become integral part of our life.

Scientists at Wake Forest Institute of Regenerative Medicine are using inkjet printers to create organs and tissues, that’s something that could change the very way of studying tissue engineering.
