1,000 Page-Per-Minute Inkjet Printer

2 researchers from the College of Judea and Samaria in Israel have designed a new kind of print head that could allow ink-jet printers to print up to 1000 pages per minute. Imagine the size of paper tray a printer featuring this technology would need just to keep printing for 1 hour. One 500 sheet paper tray usually has a height of about 3 inches, so to provide sufficient paper for this kind of printer for 1 hour, we would need one that has a total height of 30 feet ( 9.14 meters). Damn, that's just too high to fit in my house. I guess I'll have to stick with my old 10 page-per-minute HP DeskJet then.

Researchers Moshe Einat and Nissim Einat have designed a print head called JeTrix that is conceptually similar to that of a LCD monitor. The printer head features micro-reservoirs of ink, and each reservoir is responsible for an element on the page, just like how each pixel is represented on an LCD monitor. Traditional ink-jet heads need to move back and forth across paper, but this new concept enlarges the print head to the cover the entire sheet. This allows a page to be printed in just one process, which explains the remarkable printing speed.
