Instead of using a laser beam, LED printers employ a strip of light-emitting diodes (LEDs) to create the image on the drum.

In the image above you can see the silver cylinder which houses the laser diode. It is focusing the beam on a light dependent resistor to the right which looks almost like a red LED due to the ...
