HP LaserJet

LaserJet is a line of laser printers sold by HP Inc. (originally Hewlett-Packard) since 1984. The LaserJet was the world's first desktop laser printer. Canon supplies both mechanisms and cartridges for most HP laser printers; some larger A3 models use Samsung print engines.

Although laser printers date back to the early 1970s, the first one, Xerox's model 1200, was not a desktop unit. The technology base was Xerox's photocopiers. Hewlett-Packard was first with a desktop unit.

These printers (and later on all-in-one units, including scanning and faxing) have, as of 2025, a four decade plus history of serving both in offices and at home for personal/at home use.

In 2013, Advertising Age reported that HP had "78 different printers with 6 different model names."
