It was also the first HP LaserJet with an HP-designed and manufactured formatter.

The HP LaserJet IID was released in the fall of 1988, It was the first desktop laser printer capable of duplexing. A high-end, networkable printer, the LaserJet 2000 offered a duty cycle of 70,000 pages per month and the standard 300-dpi output, initially priced at $19,995. Īlso in March 1987, the LaserJet 2000 was launched. The HP LaserJet II used PCL4, improved features, more memory and fonts for a market price of $2,695. The HP LaserJet II was designed as a laser printer with correct order page output as opposed to being leveraged from the Canon PC-20 personal copier. HP introduced the mass-market laser printer, the LaserJet series II, in March 1987. The HP LaserJet family, along with Aldus PageMaker and Microsoft Windows, was central to the PC-based solution and while the design was more plebeian than Apple's product, this multi-vendor solution was available to a mass audience for the first time. In 1986, desktop publishing came to the world of IBM PCs and compatibles, after its origin on the Apple Macintosh and Apple LaserWriter. In March 1986 HP introduced the LaserJet D+, which included the LaserJet print engine and formatter but with two paper trays. It also included 512 kilobytes of memory, which was sufficient to print graphics at 300 dpi that covered about 70% of the letter-size page area. It introduced 'soft fonts', treatments like bold and italic and other features including a parallel ( Centronics) interface. The LaserJet Plus followed in September 1985, priced at US$3,995. 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. By using control codes it was possible to change the printed text style using font patterns stored in permanent ROM in the printer. The first LaserJet was a high-speed replacement for text-only daisy wheel impact printers and the noisy dot matrix printers. It was quiet compared to other contemporary printers, hence people could use the telephone while sitting near the HP LaserJet. It was ideal for printing memos, letters, and spreadsheets.

The HP LaserJet printer had high print quality, could print horizontally or vertically and produce graphics. 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. It used an 8 MHz Motorola 68000 processor and could print in a variety of character fonts. It was a 300- dpi, 8 ppm printer that sold for $3,495 with the price reduced to $2,995 in September 1985. HP introduced the first laser printer for IBM PC compatible personal computers in May 1984 at the Computer Dealers' Exhibition ( COMDEX). PostScript Cartridge for LaserJet IIP, IID, III, IIID, etc.
