The ColorQube 9200 series printers unveiled will bring groundbreaking cost efficiencies to color printing through a combination of solid ink technology and per-click pricing plans. Beyond saving money for businesses, the technology used in the ColorQube 9201/9202/9203 printers is "cleaner" than laser technology, and also much easier for office workers to deal with. In contrast to laser printers, which use cartridges containing powdered toner, Xerox' latest solid ink technology uses blocks of a crayon-like substance. Printing happens when the melts the waxy "ink sticks" and sprays the non-toxic substance on to a spinning color drum inside the machine. The printers contains 3,000 print heads apiece, with 900 ink nozzles each.
