Yes, we're gonna have to go right to ludicrous speed... when printing

The printing press, perhaps the greatest invention by modern man, could be taking another leap. A pair of engineers from the College of Judea and Samaria in Israel published their research in a recent edition of the Applied Physics Letters, which details an ink jet print head capable of printing ~1000 pages per minute.

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.

This isn’t some idea cooked up in the heads of a couple mad scientists - Moshe Einat and Nissim Einat have already experimented with a 57600 nozzle matrix print head and achieved good results as proof of their design. The implications of JeTrix mean more than just improved printer technology; it could also lead to new ways of gathering and spreading information.

“The future applications of JeTrix will be traditional, such as extremely high-speed printers for industry, offices, and homes. But we also anticipate brand-new, pioneering applications. One example is in-store book printing – where the book is printed instantly for the customer. This could enable small bookshops or even airport kiosks to carry a huge variety of books. There's also personalization – newspapers or journals printed with a customer's name, favorite topics, and suitable advertisements,” Moshe Einat told PhysOrg.com.

With additional funding and R&D, the researchers behind this technology believe that commercial products based on the JeTrix printing head could be available in two years.

Would that be 1000 identical pages per minute?
Anyway, at that speed, I imagine paper feed will be the limiting factor.

No not identical.
What about ink drying?

Actually, I think the mechanical aspects of a 1000-page-per-minute printer are the most daunting. Mechanical devices *will* fail. It's not a question of "if".. it's a question of "when". And at 1000 pages per minute, the MTBF on the mechanical components of such a printer is going to be pretty short.. and these mechanical components are going to be stressed beyond the point of anything that came before it.

Ink drying is, by comparison, a less difficult hurdle to overcome.

Since each nozzle is (basically) just opening to let some ink flow, then closing, like a regular inkjet nozzle, it doesn't matter whether the pages are the same. The nozzle isn't turned on and kept on so that it has to stop printing for a moment to switch things on or off to reconfigure the content, which would be similar to the way a regular printing press works. The nozzles are controlled individually and just told to turn on or off for each page.
