The first commercial implementation of a laser printer was the [[IBM]] [[IBM model 3800 laser printer|model 3800]] in [], used for high-volume printing of documents such as invoices and mailing labels. It is often cited as "taking up a whole room," implying that it was a primitive version of the later familiar device used with a [[personal computer]]. While large, it was designed for an entirely different purpose. Many 3800s are still in use.

The first laser printer designed for use with an individual computer was released with the [[Xerox Star]] 8010 in []. Although it was innovative, the Star was an expensive ($17,000) system that was only purchased by a small number of laboratories and institutions. After [[personal computer]]s became more widespread, the first laser printer intended for a mass market was the [[Hewlett-Packard|HP]] [[LaserJet]] 8ppm, released in [], using a [[Canon (company)|Canon]] engine controlled by HP software. The HP LaserJet printer was quickly followed by other laser printers from [[Brother Industries]], [[IBM]], and others.

Many modern color laser printers mark printouts by a nearly invisible dot [[raster]], for the purpose of identification.
