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 commercially successful laser printer. Canon supplies both mechanisms and cartridges for most HP laser printers; some larger A3 models use Samsung print engines.
These printers (and later on all-in-one units, including scanning and faxing) have, as of 2025[update], 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."
Most HP LaserJet printers employ xerographic laser-marking engines sourced from the Japanese company Canon. Due to a tight turnaround schedule on the first LaserJet, HP elected to use the controller already developed by Canon for the CX engine in the first LaserJet. In spring of 1989 The New York Times said that HP "dominates" the PC laser printer market.
The first LaserJet and the first Apple LaserWriter used the same print engine, the Canon CX engine. HP chose to use their in-house developed Printer Command Language (PCL) as opposed to Apple, which adopted the PostScript language, as developed by Adobe Systems. The use of a less-ambitious and simpler Page description language allowed HP to deliver its LaserJet to the market about a year before Apple's CX based product, and $1000 lower street price. The sharing of an identical Canon engine in two competing products continued with the LaserJet II/III and the Apple LaserWriter II, which both used the Canon LBP-CX print engine.
HP introduced the first laser printer for IBM PC compatible personal computers on May 22, 1984 at the Computer Dealers' Exhibition (COMDEX). It was a 300-dpi, 8 ppm printer that sold for $3,495 with the price reduced to $2,995 in September 1985. It used an 8 MHz Motorola 68000 processor and could print in a variety of character fonts. It was controlled using PCL3. Due to the high cost of memory, the first LaserJet only had 128 kilobytes of memory, and a portion of that was reserved for use by the controller.
The LaserJet printer had high print quality, could print horizontally or vertically and produce graphics. It was ideal for printing memos, letters, and spreadsheets. It was quiet compared to other contemporary printers, hence people could use the telephone while sitting near the LaserJet.
The first LaserJet was a high-speed replacement for text-only daisy wheel impact printers and the noisy dot matrix printers. By using control codes it was possible to change the printed text style using font patterns stored in permanent ROM in the printer. Although unsupported by HP, because the Laserjet used the same basic PCL language (PCL Level III) spoken by HP's other printers it was possible to use the Laserjet on HP 3000 multiuser systems.
