The continuation and, obviously, the end of the story with HP false advertisement. In the advertisement of LaserJet CP3505, HP claimed the printer “only require replacement toner throughout its life. And nothing else”.

This gave Kyocera grounds to bury HP to Advertising Standards Agency, which found that the claims were untrue, because each toner cartridge also included attached drums and consisted of around 60 individual parts. Cartridge for LaserJet CP3505, apart from toner, contains around 70 per cent of the printing mechanism, including drum and cleaners.

HP admitted the advertisement was basically wrong and removed the questionable phrases from it.

Here are the originators of the fuss:

American scientists please us with another achievement in printing technology. They found a new method printing finely-detailed microscopic images with an enzyme instead of ink.

Printing with enzimes instead of inkThe new method known as microcontact printing and reported to have a wide application for rapidly transferring high-resolution images onto large surfaces. However, current nanoscale printing technology depends on the diffusion of ink, and cannot reproduce details finer than one hundred nanometers in diameter.

In the new technology, “biocatalytic microcontact printing”, a nano-print is coated with an enzyme - a protein that fastens chemical reactions.

The enzyme then digests away a layer on the surface, leaving behind an imprint almost like an old-fashioned rubber stamp. Because the process does not require diffusion of ink, the resolution of microcontact printed images is about 100 times greater than conventional technology allows for.

The technique creates potential for faster, less expensive methods of nanolithography, which could be used to create complex structures for micromachines, biosensors, and other nanoscale devices, says Science Daily.
