LED printer - technical definition
An electrophotographic printer that uses a matrix of LEDs as its light source. The LED mechanism is much simpler than its laser printer counterpart. A stationary array of LEDs is used instead of numerous moving parts, and the LEDs are selectively beamed onto the drum. LED printers are available from very low-end 4 ppm personal printers to huge digital printing presses that can print more than 700 ppm. See LED.
LED Vs. Laser Printing
The LED mechanism is much simpler, because it is a stationary array of light emitting diodes (LEDs) rather than a number of moving parts.
Personal LED Printer (4 ppm)
With a 7x12" footprint, the OKIPAGE 4w from Okidata was introduced in 1996 at a breakthrough price of $299. This 4 ppm printer printed a respectable 600 dpi under Windows, and subsequent models increased the speed. (Image courtesy of Okidata.)
High-Speed LED Printer (420 ppm)
These Model 2140 digital printing presses from Oce Printing Systems use LED technology to print up to 420 ppm at 300 dpi. They accept roll-fed or boxed continuous forms paper. With an LED array 17" long, two letter-sized pages can be printed simultaneously. (Image courtesy of Oce Printing Systems USA, Inc.)
