A new laser-printing technology allows for printing high-resolution data and color images at the unprecedented resolution of 127,000 dots per inch (DPI) and with a speed of 1 nanosecond per pixel — developed by researchers at Technical University of Denmark’s DTU Nanotech and DTU Fotonik.

So this new patented method uses special plasmonic metasurfaces coated with 20 nanometers of aluminum. It is quite amazing. In the url page there is a print of Mona Lisa. The entire print is less than one iPhone pixel.

It can also save data invisible to the human eye. Examples of potential uses include serial numbers or bar codes of products, personalized products such as mobile phones with unique decorations, names, etc. and for marking parts for cars, such as instrument panels and buttons, and other information.

Scientist hope to replace conventional laser printers with this new technology.

The amazing times we live in today.

I hope they make a matching scanner. Imagine being able to back up a file system onto a sheet of paper, and then reloading it simply by scanning that sheet of paper.

Many supermarkets have printers where you can take your digital photographs and print them out as glossy postcards with the picture on the front and some lines on the back for writing a message. Using computer generated images, it's possible to store several hundred kilobytes of data.

I just want cheaper ink, it keeps going up and I am always out!

This will make my passive-aggressive comic sans notes to my roommate so much better.

Cool!
