... It relays the image information, in digital form, to the photosensitive member by use of a controllable light source, such as a laser, light-emitting diodes, light valves, or some other method of addressing many points using light.

... Smaller-sized developers, such as nonmagnetic monocomponent or liquid ones, have led to process simplifications, smaller units, and cheaper, and more durable machines. Many companies have patented or licensed basic print engine architectures that will lead to a new breed of smaller, cheaper, color copiers/printers.

... Another advance has been the development of a cartridge containing both the ink and thermal drivers produced by photolithographic methods; these drives are so inexpensive that the cartridge is disposable. In summary, inkjet technology inherently is a less complex color system than technologies requiring sequential imaging of the same spot.

... Some equipment manufacturers are now employing digital presses to receive digital data that can directly generate a plate for printing.6 This capability 4Apple Computer Color Scanner and Hewlett Packard's Scanjet currently will do color at 300 dpi, and more expensive desktop models by Agatha Gevaert and others are already doing 600 and 1,200 dpi.
