Improving LED printing

YOKOHAMA: About 25 years ago, a new type of page-printing process using an LED (light-emitting diode) was developed, which promised to make office printers smaller, quieter, more reliable and less expensive than laser printers.

LED technology uses the same fundamental electrostatic (an electrical charge is built up on an insulated object) method as the laser ROS (raster output scanner) systems of applying toner to paper.
