The
Brother Industries high speed inkjet printer in prototype form. Codenamed Cobra, this little puppy can spit out any size of print output at around 170 pages per minute. OK, you want me to back up and repeat that? Any size of printed inkjet paper output at 170 pages every sixty seconds. Demonstrated for the first time ever last week at a Brother press seminar. How are they doing it? Well….
So apparently the secret lies in the use of new Piezo Inkjet Line Head technology, which prints at 600×600 dpi, but doesn’t actually move at all. The ink is transferred at high speed as the paper passes underneath the static nozzles. (see below left - click on all images for full view)
