Why is printout by laser printers so durable?

Besides the high speed, the other main advantage of laser printers is the durability of printout. This is a consequence of the way the toner is attached to the paper. Instead of just being absorbed in the paper as in inkjet printers, the toner is actually fusing with the surface of the paper. This makes it possible for the toner to be printed not only on paper but also on other printing media. The fusion rolls will always make sure that the toner will not be smudged or harmed in any way once the paper has come out of the printer. In addition, the fusion rolls give even more flexibility for the output by allowing the heat and pressure applied by them to be controlled. Thus the user can decide how his final output will look like, which can include matte and gloss.
