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
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
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.

yes, a line printer is absolutely cool. I have seen one implemented with LED thermal heads. It can print a 3" x 5" color photo in 30s (it could be 4x faster if each color has its own head).
wait... isn't that what the laser print is doing?

I almost mentioned laser printers, but they aren't exactly a line printer entirely. The fuser functions in a line printer fashion, since the page contacts it an entire page-width at a time, and the toner drum applies toner to the paper the same way, but the laser that charges the toner drum before the toner is applied moves back and forth over the drum sort of like a dot-matrix with only one wire (or at least isn't a full page width beam).
