LED printers are laser printers' fraternal twins. Both are electrophotographic printers, which means they print by using light to draw images to be printed on photoelectric material, which attracts particles of toner to be transferred to paper. The only difference is the light source: LED or laser. LED models tend to be somewhat smaller than directly comparable laser printers, which makes them particularly suitable where space is at a premium. But for purposes of comparison, they are essentially variations on a theme, a distinction with little to no real-world difference. Key printer players that offer LED-based models (as well as laser ones) include Brother and Xerox.
