Xerox 9700
The Xerox 9700 Electronic Printing System was a high-end laser printer manufactured by Xerox Corporation beginning in 1977. Based on the Xerox 9200 copier, the 9700 printed at 300 dots-per-inch on cut-sheet paper at up to two pages per second (pps), one- or two-sided, that is simplex or duplex, landscape or portrait. Development Development of the laser printing technology behind the Xerox 9700 began in the late 1960s and was led by Gary Starkweather, with Butler Lampson and Ron Rider. It was the successor product to the Xerox 1200 Computer Printing System. Description The 9700 was intended for high-volume applications. It included a disk drive and a modified Digital Equipment Corporation (DEC) PDP-11/34 as a print controller and rasterizer. It could connect to an IBM mainframe via a parallel channel. It offered an input tray that could hold up to 2500 sheets of paper (20lb bond/75gsm) and an auxiliary input tray for an additional 400 sheets. It had two output stack ...

Laser Printing
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 ...

DECSYSTEM-20
The DECSYSTEM-20 was a family of 36-bit Digital Equipment Corporation PDP-10 mainframe computers running the TOPS-20 operating system and was introduced in 1977. PDP-10 computers running the TOPS-10 operating system were labeled ''DECsystem-10'' as a way of differentiating them from the PDP-11. Later on, those systems running TOPS-20 (on the KL10 PDP-10 processors) were labeled ''DECSYSTEM-20'' (the block capitals being the result of a lawsuit brought against DEC by Singer, which made its own System Ten model, occasionally referenced in reporting as the "System 10"). The DECSYSTEM-20 was sometimes called PDP-20, although this designation was never used by DEC. Models The following models were produced: *DECSYSTEM-2020: KS10 bit-slice processor with up to 512 kilowords of solid state RAM (The ADP OnSite version of the DECSYSTEM-2020 supported 1 MW of RAM) *DECSYSTEM-2040: KL10 ECL processor with up to 1024 kilowords of magnetic core RAM *DECSYSTEM-2050: KL10 ECL proce ...

DocuTech
DocuTech is the name given to a line of electronic production-publishing systems produced by Xerox Corporation. It allowed paper documents to be scanned, electronically edited, and then printed on demand. DocuTech systems were the last known to use the XNS protocol for networking. The very first DocuTech system, known as the DocuTech Production Publisher was announced on October 2, 1990. Its 135 page-per minute, black and white, xerographic print engine and attached finisher module were largely based on ones previously developed for the Xerox 5090 Duplicator system (announced by Xerox in 1988). However, image generation in the DocuTech was performed using a digitally driven, dual-beam, Laser ROS (Raster Output Scanner) rather than by the light-lens optics and exposure lamps found in the "analog" 5090 system. The system's scanner module allowed document scanning in a number of modes including manually from the platen or automatically using a 23 page-per-minute recirculating docum ...

GFDL
The GNU Free Documentation License (GNU FDL or GFDL) is a copyleft license for free documentation, designed by the Free Software Foundation (FSF) for the GNU Project. It is similar to the GNU General Public License, giving readers the rights to copy, redistribute, and modify (except for "invariant sections") a work and requires all copies and derivatives to be available under the same license. Copies may also be sold commercially, but, if produced in larger quantities (greater than 100), the original document or source code must be made available to the work's recipient. The GFDL was designed for manuals, textbooks, other reference and instructional materials, and documentation which often accompanies GNU software. However, it can be used for any text-based work, regardless of subject matter. For example, the free online encyclopedia Wikipedia uses the GFDL (coupled with the Creative Commons Attribution Share-Alike License) for much of its text, excluding text that was impor ...

Xerox Graphics Printer
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] |
AI Lab

Richard Stallman
Richard Matthew Stallman ( ; born March 16, 1953), also known by his initials, rms, is an American free software movement activist and programmer. He campaigns for software to be distributed in such a manner that its users have the freedom to use, study, distribute, and modify that software. Software which ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation (FSF) in October 1985, developed the GNU Compiler Collection and GNU Emacs, and wrote all versions of the GNU General Public License. Stallman launched the GNU Project in September 1983 to write a Unix-like computer operating system composed entirely of free software. With that he also launched the free software movement. He has been the GNU project's lead architect and organizer, and developed a number of pieces of widely used GNU software including among others, the GNU Compiler Collection, GNU Debugger, and GNU Emacs text editor.

Digital Printing
Digital printing is a method of printing from a Digital data, digital-based image directly to a variety of media. It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume Laser printing, laser or inkjet printers. Digital printing has a higher cost per page than more traditional offset printing methods, but this price is usually offset by avoiding the cost of all the technical steps required to make printing plates. It also allows for on-demand printing, short turnaround time, and even a modification of the image (variable data) used for each impression. The savings in labor and the ever-increasing capability of digital presses means that digital printing is reaching the point where it can match or supersede offset printing technology's ability to produce larger print runs of several thousand sheets at a low price.
