LED printer

An LED printer is a type of computer printer similar to a laser printer. Such a printer uses a light-emitting diode (LED) array as a light source in the printhead instead of the laser used in laser printers and, more generally, in the xerography process. The LED bar pulse-flashes across the entire page width and produces the image on the print drum or belt as it moves past. LEDs are more efficient and reliable than conventional laser printers, since they have fewer moving parts, allowing for less mechanical wear. Depending on design, LED printers can have faster rates of print than some laser-based designs, and are generally cheaper to manufacture. In contrast to LED printers, laser printers require combinations of rotating mirrors and lenses that must remain in alignment throughout their use. The LED print head has no moving parts, and the individual assemblies tend to be more compact.
