Daisy Wheel Printing
Daisy wheel printing is an impact printing technology invented in 1970 by Andrew Gabor at Diablo Data Systems. It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to three times faster. Daisy wheel printing was used in electronic typewriters, word processors and computers from 1972. The daisy wheel is so named because of its resemblance to the Asteraceae, daisy flower. By 1980 daisy wheel printers had become the dominant technology for high-quality text printing, grossly impacting the dominance of manual and electric typewriters, and forcing dominant companies in that industry, including Brother Industries, Brother and Silver Seiko Ltd., Silver Seiko to rapidly adapt — and new companies, e.g., Canon Inc., Canon and Xerox, to enter the personal and office market for daisy wheel typewriters. The personal and office printing industry would soon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xerox Roman PS Daisywheel - Mono
Xerox Holdings Corporation (, ) is an American corporation that sells print and electronic document, digital document products and services in more than 160 countries. Xerox was the pioneer of the photocopier market, beginning with the introduction of the Xerox 914 in 1959, so much so that the word ''xerox'' is commonly used as a synonym for ''photocopy''. Xerox is headquartered in Norwalk, Connecticut, though it is incorporated in New York (state), New York with its largest group of employees based around Rochester, New York, the area in which the company was founded. As a large developed company, it is consistently placed in the list of Fortune 500 companies. The company purchased Affiliated Computer Services for $6.4 billion in early 2010. On December 31, 2016, Xerox separated its business process service operations, essentially those operations acquired with the purchase of Affiliated Computer Services, into a new publicly traded company, Conduent. Xerox focuses on its docu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qume
Qume was a manufacturer of daisy-wheel printers originally located in Hayward, California, later moving to San Jose. Around 1980, it also opened a manufacturing facility in Puerto Rico. It once dominated the daisy-wheel market. As the market for its printers declined in the 1980s, the company developed a line of computer terminals. It was founded by David S. Lee and Robert E. SchroederThe Startup Game: Inside the Partnership between Venture Capitalists and Entrepreneurs, William H. Draper III, St. Martin's Press, 1/4/2011, ASIN B004CYERLI, page 168 in 1973, grew to become the largest printer company in the world, and was acquired by ITT Corporation for an unprecedented $164M in 1978. It remained a division of ITT until its acquisition by Wyse Technology sometime before 1995. Qume also manufactured floppy diskette drives, particularly 5.25" ones, but it also manufactured 8" diskette drives as well. Qume's diskette drives were included in some IBM PC models, such as the Portabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Laserwriter
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.H. A. Tucker: Desktop Publishing.'' In: Maurice M. de Ruiter: ''Advances in Computer Graphics III.'' Springer, 1988, , P. 296.Michael B. Spring: Electronic printing and publishing: the document processing revolution.'' CRC Press, 1991, , Page 46. History Development of laser printing Laser printing traces its history to efforts by Gary Starkweather at Xerox in 1969, which resulted in a commercial system called the Xerox 9700. IBM followed this with the IBM 3800 system in 1976. Both machines were large, room-filling devices handling the combined output of many users.Benji Ed ...

Typeface
A typeface (or font family) is a design of Letter (alphabet), letters, Numerical digit, numbers and other symbols, to be used in printing or for electronic display. Most typefaces include variations in size (e.g., 24 point), weight (e.g., light, bold), slope (e.g., italic), width (e.g., condensed), and so on. Each of these variations of the typeface is a font. There are list of typefaces, thousands of different typefaces in existence, with new ones being developed constantly. The art and craft of designing typefaces is called type design. Designers of typefaces are called type designers and are often employed by type foundry, type foundries. In desktop publishing, type designers are sometimes also called "font developers" or "font designers" (a typographer is someone who ''uses'' typefaces to design a page layout). Every typeface is a collection of glyphs, each of which represents an individual letter, number, punctuation mark, or other symbol. The same glyph may be used for ch ...

ASCII
ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable character, printable and 33 control character, control characters a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers; for example, the first 128 code points of Unicode are the same as ASCII. ASCII encodes each code-point as a value from 0 to 127 storable as a seven-bit integer. Ninety-five code-points are printable, including digits ''0'' to ''9'', lowercase letters ''a'' to ''z'', uppercase letters ''A'' to ''Z'', and commonly used punctuation symbols. For example, the letter is represented as 105 (decimal). Also, ASCII specifies 33 non-printing control codes which originated with ; most of which are now obsolete. The control cha ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the early 1960s. The company produced a series of machines known as the Programmed Data Processor, PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diablo 630
The Diablo 630 is a discontinued daisy wheel style computer printer sold by the Diablo Data Systems division of the Xerox Corporation beginning in 1980. The printer is capable of letter-quality printing; that is, its print quality is equivalent to the quality of an IBM Selectric typewriter or printer, the de facto quality standard of the time. Overview The printer is capable of this quality at a nominal speed of 30 characters per second (roughly twice the speed of the Selectric). Several technologies were introduced to enable this quality and speed: * The lightweight daisy wheel is rotated by a closed-loop servo and can be positioned rapidly and accurately. Because the wheel can turn in either direction, the next character is never more than 180° away from the previous character (and related characters are grouped together so the average "seek" is much less than 180°). * Like the "typeball" element on a Selectric, the daisy wheel can be easily changed, allowing for a wide va ...

Redactron
A word processor is an electronic device (later a computer software application) for text, composing, editing, formatting, and printing. The word processor was a stand-alone office machine developed in the 1960s, combining the keyboard text-entry and printing functions of an electric typewriter with a recording unit, either tape or floppy disk (as used by the Wang machine) with a simple dedicated computer processor for the editing of text. Although features and designs varied among manufacturers and models, and new features were added as technology advanced, the first word processors typically featured a monochrome display and the ability to save documents on memory cards or diskettes. Later models introduced innovations such as spell-checking programs, and improved formatting options. As the more versatile combination of personal computers and printers became commonplace, and computer software applications for word processing became popular, most business machine companies ...

Selectric
The IBM Selectric (a portmanteau of "selective" and "electric") was a highly successful line of electric typewriters introduced by IBM on 31 July 1961. Instead of the "basket" of individual typebars that swung up to strike the ribbon and page in a typical typewriter of the period, the Selectric had a chrome-plated plastic "element" (frequently called a "typeball", or less formally, a "golf ball") that rotated and tilted to the correct position before striking the paper. The element could be easily interchanged to use different fonts within the same document typed on the same typewriter, resurrecting a capability which had been pioneered by typewriters such as the Hammond and Blickensderfer in the late 19th century. The Selectric also replaced the traditional typewriter's horizontally moving carriage with a roller (platen) that turned to advance the paper vertically while the typeball and ribbon mechanism moved horizontally across the paper. The Selectric mechanism was notable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ink Jet Printer
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper or 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 concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s. While working at Canon in Japan, Ichiro Endo suggested the idea for a "bubble jet" printer, while around the same time Jon Vaught at Hewlett-Packard (HP) was developing a similar idea. In the late 1970s, inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, HP and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Epson a ...

Laser Printer
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a Electric charge, negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (toner (printing), 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 computer printer, printers employ a Xerography, 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. The laser printer was invented at Xerox PARC (company), PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM ...
