In contrast to LED printers, laser printers require combinations of rotating mirrors and lenses that must remain in alignment throughout their use. The LED print head has no moving parts, and the individual assemblies tend to be more compact.

Yeah, thought as much. LEDs are cheaper than lasers, so stack a bunch of them in a line, polarise the drum, bam, you have an image.

Basically, this is the only advantage. And laser heads break very very rarely. You litelarly have to drop the printer from a considerable height in order to break the laser head mechanism.

But, I can see the appeal. Laser heads and mechanisms are more expensive to manufacture.
