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.
