Personal Printer Data Stream
{{inline, date=December 2018 Personal Printer Data Stream is a general name for a family of page description language used by IBM printers, which includes all Proprinter, Quietwriter, Quickwriter, LaserPrinter 4019, and LaserPrinter 4029 commands. PPDS was introduced to control printers in 1981 with the launch of IBM Graphics Printer 5152. Originally called IBM ASCII, Proprinter, Quickwriter, or Quietwriter data stream, the name was changed to PPDS when the IBM LaserPrinter was introduced in 1989. PPDS has different levels of functions that are all upward compatible. Although many laser or inkjet printers do not support PPDS, those that support binary printer languages still use the ESC syntax, which include Printer Command Language versions 1 to 5 and the Epson ESC/P command set. PPDS levels Level 1 Level 1 is the basic level of PPDS, providing the basic services needed by any printer. This level is represented by the 9- and 24-pin Proprinter family of printers.

Page Description Language
In digital printing, a page description language (PDL) is a computer language that describes the appearance of a printed page in a higher level than an actual output bitmap (or generally raster graphics). An overlapping term is printer control language, which includes Hewlett-Packard's Printer Command Language (PCL). PostScript is one of the most noted page description languages. The markup language adaptation of the PDL is the page description markup language. Page description languages are text (human-readable) or binary data streams, usually intermixed with text or graphics to be printed. They are distinct from graphics application programming interfaces (APIs) such as GDI and OpenGL that can be called by software to generate graphical output. Notable examples Various page description languages exist: * AFP, Advanced Function Presentation ( IBM) * Apple Raster, formerly known as URF, used by the AirPrint protocol. * Canon GARO, Graphic Arts language with Raster Operations ...

Printer Command Language
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. PCL is occasionally and incorrectly said to be an abbreviation for ''Printer Control Language'' which actually is another term for page description language. PCL levels 1 through 5 overview PCL levels 1 through 5e/5c are command-based languages using control sequences that are processed and interpreted in the order they are received. At a consumer level, PCL data streams are generated by a print driver. PCL output can also be easily generated by custom applications. *PCL 1 was introduced in 1984 on the HP ThinkJet 2225 and provides basic text and graphics printing with a maximum resolution of 1 ...

ESC/P
ESC/P, short for Epson Standard Code for Printers and sometimes styled Escape/P, is a printer control language developed by Epson to control computer printers. It was mainly used in dot matrix printers and some inkjet printers, and is still widely used in many receipt thermal printers. During the era of dot matrix printers, it was also used by other manufacturers (e.g., NEC), sometimes in modified form. At the time, it was a popular mechanism to add formatting to printed text, and was widely supported in software. Derivation ESC/P derives its name from the start of the escape sequences used, which start with the escape character ESC (ASCII code 27). As an example, ''ESC E'' will switch to printing in bold font, while ''ESC F'' switches off bold printing. The ESC/P control codes are sometimes also referred to as Epson LQ codes, as they were made popular by the Epson LQ series of dot matrix printers, even though ESC/P was introduced long before LQ printers. Variants There are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dot Matrix Printer
A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper. The combination of these dots forms a dot matrix image. They were also known as serial dot matrix printers. While inkjet and laser printers technically exhibit dot matrix printing, they work differently than impact "dot matrix printers" and can deposit ink or toner at higher dot resolutions more quickly, with less inherent noise. The impact printer has the ability to make copies using multi-part forms, unlike an inkjet or laser printer. History In the 1970s and 1980s, dot matrix impact printers were generally considered the best combination of cost and versatility, and until the 1990s were by far the most common form of printer used with personal and home computers.

Lexmark
Lexmark International, Inc. is a privately held American company that manufactures laser printers and imaging products. The company is headquartered in Lexington, Kentucky. Since 2016 it has been jointly owned by a consortium of three multinational companies: Apex Technology, PAG Asia Capital, and Legend Capital. History Lexmark was formed on March 27, 1991 when investment firm Clayton & Dubilier completed a leveraged buyout of IBM Information Products Corporation, the printer, typewriter, and keyboard operations of IBM. Lexmark became a publicly traded company on the New York Stock Exchange on November 15, 1995. By 2016, the company struggled to keep corporate clients that are cutting costs and the consumers who are shifting to mobile devices from personal computers. It was reported in April 2016 that Lexmark would be acquired by Apex Technology and PAG Asia Capital for US$3.6 billion. Lexmark was set to be acquired at $40.50 per share in the transaction.
