The lifespan of a laser printer varies according to a number of factors, such as its usage, its upkeep, and the model quality. As print quality gradually declines over time, laser printers typically last between 3 and 5 years. When maintained properly, black-and-white printers have been known to last up to ten years. However, by giving your laser printer the proper attention and carrying out regular maintenance, you can lengthen its lifespan.
