The toner powder contained within the Hewlett Packard CB383A comes infused with ColorSphere technology. This means the toner particles in the CB383A magenta toner cartridge are more uniformed in shape and size give. Resulting in coloured prints with a smooth transition between colours and without visible gaps in solid printing. The CB383A and other genuine Hewlett Packard toner cartridges give high gloss results and are capable of printing consistently even at higher speeds.
