Foomatic
Foomatic is a configurable printing filter. It uses PostScript Printer Description, PPD files as configuration to generate appropriate output for a given printer. It is spooler independent which means it can be used with Common Unix Printing System (CUPS), LPRng and others. It uses Ghostscript in the background, using options according to the PPD file of the printer. Currently it is developed by the OpenPrinting workgroup of the Linux Foundation. Operation Like CUPS, foomatic supposes that applications will produce output in PostScript. If the output spools to a PostScript printer, no further action is needed. Otherwise, the most generic way to act is: * Create a Raster graphics, raster file from the PostScript (ps2raster, usually using Ghostscript in the background) * Create a printer language, printer-language file from the raster data (raster2xxx, using the raster driver of the target printer) * Send the printer-language file to the printer But if foomatic-rip "knows" about t ...

CUPS
CUPS (formerly an acronym for Common UNIX Printing System) is a modular computer printer, printing system for Unix-like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a Server (computing), host that can accept print jobs from client (computing), client computers, process them, and send them to the appropriate printer. CUPS consists of a print spooler and scheduler, a filter system that converts the print data to a format that the printer will understand, and a backend system that sends this data to the print device. CUPS uses the Internet Printing Protocol (IPP) as the basis for managing print jobs and queue (printing), queues. It also provides the traditional command line interfaces for the System V printing system, System V and Berkeley printing system, Berkeley print systems, and provides support for the Berkeley print system's Line Printer Daemon protocol and limited support for the Server Message Block (SMB) protoc ...

Line Printer Daemon Protocol
The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) is a network printing protocol for submitting print jobs to a remote printer. The original implementation of LPD was in the Berkeley printing system in the BSD UNIX operating system; the LPRng project also supports that protocol. The Common Unix Printing System (or CUPS), which is more common on modern Linux distributions and also found on Mac OS X, supports LPD as well as the Internet Printing Protocol (IPP). Commercial solutions are available that also use Berkeley printing protocol components, where more robust functionality and performance is necessary than is available from LPR/LPD (or CUPS) alone (such as might be required in large corporate environments). The LPD Protocol Specification is documented in RFC 1179. Usage A server for the LPD protocol listens for requests on TCP port 515. A request begins with a byte containing the request code, followed by the arguments to the request, and is termi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghostscript
Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization or rendering of such page description language files, for the display or printing of document pages, and the conversion between PostScript and PDF files. Features Ghostscript can be used as a raster image processor (RIP) for raster computer printers—for instance, as an input filter of line printer daemon—or as the RIP engine behind PostScript and PDF viewers. It can also be used as a file format converter, such as PostScript to PDF converter. The ps2pdf conversion program comes with the Ghostscript distribution. Ghostscript can also serve as the back-end for PDF to raster image (png, tiff, jpeg, etc.) converter; this is often combined with a PostScript printer driver in "virtual printer" PDF creators. As it takes the form of a language interpreter, Ghostscript can also be used as a g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

HP LaserJet
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 first popular desktop laser printer. Canon supplies both mechanisms and cartridges for most HP laser printers; some larger A3 models use Samsung print engines. Technology Most HP LaserJet printers employ xerographic laser-marking engines sourced from the Japanese company Canon. Due to a very tight turnaround schedule on the first HP LaserJet, HP elected to use the controller already developed by Canon for the CX engine in the first HP LaserJet. The first HP LaserJet and the first Apple LaserWriter used the same print engine, the Canon CX engine. HP chose to use their in-house developed Printer Command Language (PCL) as opposed to Apple, which adopted the PostScript language, as developed by Adobe Systems. The use of a less-ambitious and simpler Page description language allowed HP to deliver its LaserJet to the market about a ...

PostScript
PostScript (PS) is a page description language in the electronic publishing and desktop publishing realm. It is a dynamically typed, concatenative programming language. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. History The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. At that time Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a succ ...

Printer 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 Operation ...
