You may have noticed that LED printers can also be found alongside laser printers in the stores. They look the same, and even the salesperson probably insisted they offer the same performance and benefits.
So what’s the difference between a laser and an LED printer then? Both laser and LED printers use light to draw the image onto a rotating photosensitive drum or belt. The main difference between an LED and a laser printer is the light source used.
Laser printers use a laser beam which is bounced off a moving mirrored surface to reach the drum. There the beam creates a static charge which will attract toner, which is then transferred from the drum onto the page via a quick baking process. During the printing process, the laser scans across the page in sequence, line by line, dot by dot.
