One is telling about new Epson printer producing trillions of colors:
The Photo R1900 implements a “groundbreaking” technology that allows for “smoother images and color control” coupled with UltraChrome™ Hi-Gloss2 Ink. The UltraChrome™ Hi-Gloss2, apart from common cyan, magenta and yellow inks, also features matte black, photo black, red, orange (replacement for blue) and gloss optimiser.In another article you will find out about the history of laser printers:
All in all, Epson Stylus Photo R1900 is said to produce 18,446,774 trillion colors. Such a tremendous amount of colors offers “a wider color gamut, natural skin tones and consistent color with a smooth gloss finish.”

On October 22, 1938, when American inventor Chester Carlson together with German immigrant Otto Kornei first transferred an image from a glass microscope slide to a sheet of wax paper using method later called electrophotography.Next post reveals what hazards laser printers may cause:
Canadian Broadcasting Company sponsored its own study on that issue. The research was conducted in three different locations in Winnipeg by placing particle monitors above printers in the offices. Basically, the results of this new study support those of the Australian study: laser printers do emit in large volumes ultra-fine particles that apparently originate from the use of toner.Read these and other posts at Toner Cartridge Depot blog.
