Deskjet is a brand name for inkjet printers manufactured by Hewlett-Packard. [1] These printers range from small domestic to large industrial models, although the largest models in the range have generally been dubbed DesignJet. [2] The Macintosh-compatible equivalent was branded as the Deskwriter and competed with Apple's StyleWriter, and the all-in-one equivalent is called OfficeJet.
HP began making inkjet printers with the HP Thinkjet (models HP 2225A and HP 2225B) in 1984. [3] In 1988, HP introduced the first DeskJet. It included a built-in cut sheet feeder, 2 ppm, and 300 dpi. This was followed by the DeskJet Plus in 1989. It offered a landscape printing ability. The DeskJet 500 was introduced in 1990, offering a faster printing speed of 3 ppm. Meanwhile, HP introduced the DeskWriter for the Macintosh in 1989, based on the DeskJet 500.
By 1987, the world's first full-color inkjet printer, the PaintJet, was introduced. It was so successful that HP introduced a version of the DeskJet capable of color printing, the DeskJet 500C, in October 1991, which is also HP's first 300 dpi color printer, offering 4 minutes per page in color, using a swappable either black or CMY print head cartridge. It was replaced by the DeskJet 550C in October 1992, HP's first dual-cartridge color DeskJet, offering a real black instead of mixed black ink in color prints, using both the 500C's cartridges at once. The DeskJet 560C followed in March 1994, which introduced HP ColorSmart to intelligently analyze documents for the best color output.
Meanwhile, HP introduced the DeskJet Portable (3 ppm) in 1992. It was designed to be easily portable. It was targeted at mobile professionals. It was replaced by the HP DeskJet 310 (4 ppm B&W, 4 minutes per page color) in 1993, the HP DeskJet 320 in 1994, the HP DeskJet 340 (2 minutes per page color) in 1995, and the HP DeskJet 350 and 350CBi (5 ppm B&W, 2 ppm color) in 2000.
HP continued to make black-and-white-only inkjet printers with the HP DeskJet 510 (1992) and 520 (1994). The HP DeskJet 520 introduced resolution enhancement technology, or REt, to HP inkjet printers. It was also HP's last black-and-white-only inkjet printer. The HP DeskJet 500, 510, 520, 500C, 550C, and 560C were all replaced by the HP DeskJet 540 (3 ppm B&W, 1.5 minutes per page color). A one-pen inkjet printer, color was optional. Also it introduced a different industrial design.
HP's high-end printer line started with the HP DeskJet 1200C, introduced in 1993, offering 6 ppm B&W, and 1 ppm color. This was replaced by the HP DeskJet 1600C (1995), offering 9 ppm B&W, and 4 ppm color, which offered a successor, the HP DeskJet 1600CN (1996), the 1600C with built-in networking.
In May 1995, HP unveiled the HP Deskjet and Deskwriter 660C which contained both black and tricolor inket cartridges that provided 600 by 600 dpi B&W at 4ppm and 600 by 300 dpi color printing, up to 1.5 ppm. The HP Deskjet 850C and 855C were released in September of that year and featured HP's Color Resolution Enhancement technology (C-Ret) capable of the same resolutions of the 660C but with print speeds of 6 ppm B&W and up to 2 ppm color. [4]
HP replaced the PaintJet XL300 and the DeskJet 1600C/1600CN with the HP DeskJet 1000C/1100C/1120C in 1998, HP's first A3 inkjet printers under the DeskJet brand. These printers were replaced by the HP DeskJet 1220C in 2000, offering 12 ppm in B&W, and 10 ppm in color.
Vivid, enduring HP Vivera inks were introduced with the HP Deskjet 6540 in 2004, offering breakthrough printing speeds of up to 30 ppm in black-and-white, and 20 ppm in color.
HP all-in-one inkjet printers under the Deskjet brand exist, starting with the HP Deskjet F380 printer/scanner/copier, introduced in 2006, using HP Vivera inks, and offering print speeds of 20 ppm in black-and-white, and 14 ppm in color.
Today, HP sells various DeskJets. The current line of HP DeskJets include the HP DeskJet 1000/2000/3000/4000. HP DeskJet 1000s usually are print only, whereas the DeskJet 2000/3000/4000 typically offers scanners built in. The 4000 series typically have both ADF(Automatic Document Feeder) scanning and flatbed scanning. Also in HP's offerings of family/home office printers include the ENVY, OfficeJet(Pro), Smart Tank and some LaserJets.
In the field of computing, a printer is considered a peripheral device that serves the purpose of creating a permanent representation of text or graphics, usually on paper. While the majority of outputs produced by printers are readable by humans, there are instances where barcode printers have found a utility beyond this traditional use. Different types of printers are available for use, including inkjet printers, thermal printers, laser printers, and 3D printers.
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated to permanently fuse the text, imagery, or both, to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by reflecting light off an existing document onto the exposed drum.
Dot matrix printing, sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires and typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. They were also known as serial dot matrix printers. Unlike typewriters or line printers that use a similar print mechanism, a dot matrix printer can print arbitrary patterns and not just specific characters.
A page printer is a computer printer which processes and prints a whole page at a time, as opposed to printers which print one line or character at a time such as line printers and dot-matrix printers. Page printers are often all incorrectly termed “laser printers”—although virtually all laser printers are page printers, other page printing technologies also exist.
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals.
The LaserWriter is a laser printer with built-in PostScript interpreter sold by Apple, Inc. from 1985 to 1988. It was one of the first laser printers available to the mass market. In combination with WYSIWYG publishing software like PageMaker, that operated on top of the graphical user interface of Macintosh computers, the LaserWriter was a key component at the beginning of the desktop publishing revolution.
Giclée describes digital prints intended as fine art and produced by inkjet printers. The term is a neologism, ultimately derived from the French word gicleur, coined in 1991 by printmaker Jack Duganne. The name was originally applied to fine art prints created on a modified Iris printer in a process invented in the late 1980s. It has since been used widely to mean any fine-art printing, usually archival, printed by inkjet. It is often used by artists, galleries, and print shops for their high quality printing, but is also used generically for art printing of any quality.
Thermal-transfer printing is a digital printing method in which material is applied to paper by melting a coating of ribbon so that it stays glued to the material on which the print is applied. It contrasts with direct thermal printing, where no ribbon is present in the process.
LaserJet as a brand name identifies the line of laser printers marketed by the American computer company Hewlett-Packard (HP). The HP 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.
StyleWriter is a line of inkjet serial printers by Apple, targeted mainly towards consumers. They produced print quality that was better than the dot matrix ImageWriters, and were cheaper than the LaserWriters. All but a few models contained Canon print engines, while the last few were re-badged HP Deskjet printers. When Steve Jobs returned to Apple in 1997, he discontinued most of the company's accessory product lines, including the StyleWriter and LaserWriter.
Printer Command Language, more commonly referred to as PCL, is a page description language (PDL) developed by Hewlett-Packard as a printer protocol and has become a de facto industry standard. Originally developed for early inkjet printers in 1984, PCL has been released in varying levels for thermal, matrix, and page printers. HP-GL/2 and PJL are supported by later versions of PCL.
An ink cartridge or inkjet cartridge is the component of an inkjet printer that contains the ink to be deposited onto paper during printing. It consists of one or more ink reservoirs and can include electronic contacts and a chip to exchange information with the printer.
HP Labs is the exploratory and advanced research group for HP Inc. HP Labs' headquarters is in Palo Alto, California and the group has research and development facilities in Bristol, UK. The development of programmable desktop calculators, inkjet printing, and 3D graphics are credited to HP Labs researchers.
The HP LaserJet 4 is a group of monochrome laser printers produced in the early to mid-1990s as part of the LaserJet series by Hewlett-Packard (HP). The 4 series has various models, including the standard LaserJet 4 for business use, the 4L for personal use and the 4P for small businesses. Additional models included the 4Si model, created as a heavy-duty business printer, and the 4V model, a B-size printer for desktop publishing and graphic artists. There are also PostScript variants of these machines with the '4M' designation, where M stands for, but is not limited to, usage with an Apple Macintosh. Hewlett-Packard also released an upgraded version of the LaserJet 4/4M known as the 4 Plus ('4+')/4M Plus ('4M+').
The NeXT Laser Printer [NeXT PN N2000] was a 400 DPI PostScript laser printer, sold by NeXT from late 1988 to 1993 for the NeXTstation and NeXTcube workstations and manufactured by Canon Inc. It included an adjustable paper tray, which enabled it to print on several paper sizes including A4, letter-size, and those of legal and envelope varieties. It was very similar to other printers based on the Canon SX engine, such as the Apple LaserWriter II series and HP LaserJet II/III, although those other printers only printed at 300x300 dpi. Some parts are interchangeable with the LaserJet II/III.
Solid ink is a type of ink used in printing. Solid ink is a waxy, resin-based polymer that must be melted prior to usage, unlike conventional liquid inks. The technology is used most often in graphics and large-format printing environments where color vividness and cost efficiency are important.
The LaserJet 4000 series is Hewlett-Packard's medium-duty monochrome laser printer range and the successor to the LaserJet 5 series.
Edgeline printing is a printing technology based on ink jet printing. In the case of traditional ink jet printers, the tiny matchbox size print head moves back and forth. This has inherent delay and requires two dimensional movement: (a) movement of print head; and (b) movement of paper. These movements are one of the reasons for the time lag in the ink jet printing.
The HP 4xx family of Designjet plotters was made to enable the printing of large-format 24- to 36-inch wide monochrome or color plotting of technical documents and color photographs. HP no longer supports this plotter.
