Any way you look at it, the 17-inch P800 surpasses its celebrated predecessor.
The P800 is the prototype for Epson's new generation of UltraChrome HD professional-level pigment-based inks. It comes equipped with 9 inks - matte black, photo black, light black and light light black, cyan, light cyan, vivid magenta, vivid light magenta, and yellow. And as part of Epson's industry-leading MicroPiezo AMC print head design, each colour of ink is dispersed through 180 minuscule nozzles. The result? Denser colours, smooth gradations, the deepest most extraordinary blacks, and a range of printing resolutions up to a lifelike 2880x1440 dpi. In other words, unprecedented quality for a 17-inch desktop inkjet.
Also, there is a handy Roll Paper Option for P800 - It's an option that lets you print in roll-based media from 13" to 17' wide!
