Scientists also excited at the prospect of charging $8,234 for an ink cartridge that will allow you to print half of a UPS return label.

FTA: "The scientists replicated a well-known picture of a woman's face, called Lena. Originally published in Playboy, Lena has become a traditional test for imaging processing quality."

There are pictures in Playboy?

Oh great, now my dot matrix printer seems outdated. Curse you technology.

You'd need a microscope to see any jaggies. Or be so near-sighted you can hold something less than 1mm from your eye and make it out.

FTFA:

(Magazines typically print images at 300 dots per inch.)
That is not true. Magazines are typically printed on web offset printing presses at 2400dpi or higher (art magazines at up to 4800dpi or more). Color (or grayscale) photos and other images not made of pure solid ink colors are "halftone screened" so that they appear to be made of dots at varying angles. These dots are made of pixels, and become larger or smaller to make that color of ink appear lighter or darker in that region. So, yes, an image printed on a 2400dpi printer may be "screened" at 200−300 lines per inch (lpi) or so.

I worked on a printer that imaged ~3 micron dots, 8000 per inch. The dots were black or white. The result was ~10 bits per pixel grayscale at ~300 dpi.

Unfortunately, it can only print on 8-foot by 11-foot sheets of paper.

How does their printer have anything to do with an electronic display?

/still the highest resolution tablet, and highest resolution laptop display on the planet
//Somehow high resolution is a bad thing?
