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.

So, don't build a 1000 ppm printer. I think this 1000 ppm spec is just marketing buzz for the fact that the proper amount of ink can get out of the nozzles in 1/1000 of a minute, as I wrote in a previous comment.

In that light the "ppm" spec is really not exiting at all, compared to the speed of todays inkjet printer nozzles. They must be way faster than this to allow printing a page line after line in reasonable time.

Whats interesting is that you can print by stamping a page at a time in a prebound book. At whatever speed this will be faster and less complicated than having to print on flat paper and afterwards do the book binding. At least that is my interpretation of the news story.
