System V Printing System
The printing subsystem of UNIX System V is one of several standardized systems for printing on Unix, and is typical of commercial System V-based Unix versions such as Solaris and SCO OpenServer. A system running this print architecture could traditionally be identified by the use of the user command as the primary interface to the print system, as opposed to the BSD command (though some systems provide as an alias to ). Typical user commands available to the System V printing system are: *: the user command to print a document *: shows the current print queue *: deletes a job from the print queue *: a system administration command that configures the print system *: a system administration command that moves jobs between print queues History In the Unix programming model, device files are special files that act as access points to peripheral devices such as printers. For example, the first line printer on a Unix system might be represented by a file in the device () director ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printer (computing)
A printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. History The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. He also had plans for a curve plotter, which would have been the first computer graphics printer if it was built. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for electrostatically depositing ink on controlled areas of a receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. The ink was a red sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

Berkeley Printing System
The Berkeley printing system is one of several standard architectures for printing on the Unix platform. It originated in 2.10BSD, and is still used to varying degrees in BSD derivatives such as FreeBSD, NetBSD, OpenBSD, and DragonFly BSD. A system running this print architecture could traditionally be identified by the use of the user command ''lpr'' as the primary interface to the print system, as opposed to the System V printing system ''lp'' command. Typical user commands available to the Berkeley print system are: *''lpr'' — the user command to assign a job to the print queue *''lpq'' — shows the current print queue *''lprm'' — deletes a job from the print queue The ''lpd'' program is the daemon with which those programs communicate. These programs support the line printer daemon protocol, so that other machines on a network can submit jobs to a print queue on a machine running the Berkeley printing system, and so that the Berkeley printing system user commands ca ...

Common Unix Printing System
CUPS (formerly an acronym for Common UNIX Printing System) is a modular printing system for Unix-like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from 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 queues. It also provides the traditional command line interfaces for the System V and 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) protocol. System administrators can configure the device drivers which CUPS supplies by editing text files in Adobe's PostScript ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenSolaris
OpenSolaris () is a discontinued open-source computer operating system for SPARC and x86 based systems, created by Sun Microsystems and based on Solaris. Its development began in the mid 2000s and ended in 2010. OpenSolaris was developed as a combination of several software ''consolidations'' that were open sourced starting with Solaris 10. It includes a variety of free software, including popular desktop and server software. It is a descendant of the UNIX System V Release 4 (SVR4) code base developed by Sun and AT&T in the late 1980s and is the only version of the System V variant of UNIX available as open source. After Oracle's acquisition of Sun Microsystems in 2010, Oracle discontinued development of OpenSolaris in house, pivoting to focus exclusively on the development of the proprietary Solaris Express (now Oracle Solaris). Prior to Oracle's close-sourcing Solaris, a group of former OpenSolaris developers began efforts to fork the core software under the name ...

Open Source Software
Open-source software (OSS) is Software, computer software that is released under a Open-source license, license in which the copyright holder grants users the rights to use, study, change, and Software distribution, distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to online collaboration, participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2024 estimate of the value of open-source software to firms is $8.8 trillion, as firms would need to spend 3.5 times the amount they currently do without the use of open source software. Open-source code can be used for studying and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SUSE Linux
openSUSE () is a free and open-source Linux distribution developed by the openSUSE project. It is offered in two main variations: ''Tumbleweed'', an upstream rolling release distribution, and ''Leap'', a stable release distribution which is sourced from SUSE Linux Enterprise. The openSUSE project is sponsored by SUSE of Germany; the company released the first version as SUSE Linux in 1994. Its development was opened up to the community in 2005, which marked the creation of openSUSE.

Slackware
Slackware is a Linux distribution created by Patrick Volkerding in 1993. Originally based on Softlanding Linux System (SLS), Slackware has been the basis for many other Linux distributions, most notably the first versions of SUSE Linux distributions, and is the oldest distribution that is still maintained. Slackware aims for design stability and simplicity and to be the most "Unix-like" Linux distribution. It makes as few modifications as possible to software packages from upstream and tries not to anticipate use cases or preclude user decisions. In contrast to most modern Linux distributions, Slackware provides no graphical installation procedure and no automatic dependency resolution of software packages. It uses plain text files and only a small set of shell scripts for configuration and administration. Without further modification it boots into a command-line interface environment. Because of its many conservative and simplistic features, Slackware is often considered to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Hat Linux
Red Hat Linux was a widely used commercial open-source Linux distribution created by Red Hat until its discontinuation in 2004. Early releases of Red Hat Linux were called Red Hat Commercial Linux. Red Hat published the first non-beta release in May 1995. It included the Red Hat Package Manager as its packaging format, and over time RPM has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux. In 2003, Red Hat discontinued the Red Hat Linux line in favor of Red Hat Enterprise Linux (RHEL) for enterprise environments. Fedora Linux, developed by the community-supported Fedora Project and sponsored by Red Hat, is a free-of-cost alternative intended for home use. Red Hat Linux 9, the final release, hit its official end-of-life on April 30, 2004, although updates were published for it through 2006 by the Fedora Legacy project until the updates were discontinued in early 2007.

Mandriva Linux
Mandriva Linux, a fusion of the French distribution Mandrake Linux and the Brazilian distribution Conectiva Linux, is a discontinued Linux distribution developed by Mandriva S.A. Each release lifetime was 18 months for base updates (Linux, system software, etc.) and 12 months for desktop updates ( window managers, desktop environments, web browsers, etc.). Server products received full updates for at least five years after their release. The last release of Mandriva Linux was in August 2011. Most developers who were laid off went to Mageia. Later on, the remaining developers teamed up with community members and formed OpenMandriva, a continuation of Mandriva. History The first release of Mandrake was based on Red Hat Linux (version 5.1) and K Desktop Environment 1 in July 1998. After that, it moved away from the Red Hat standard and Red Hat inspiration and influence on its own design and implementation, and became a completely separate distribution. Mandrake included a num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debian
Debian () is a free and open-source software, free and open source Linux distribution, developed by the Debian Project, which was established by Ian Murdock in August 1993. Debian is one of the oldest operating systems based on the Linux kernel, and is the basis of List of Linux distributions#Debian-based, many other Linux distributions. As of September 2023, Debian is the second-oldest Linux distribution still in active development: only Slackware is older. The project is coordinated over the Internet by a team of volunteers guided by the List of Debian project leaders, Debian Project Leader and three foundational documents: the Debian Social Contract, the Debian Constitution, and the Debian Free Software Guidelines. In general, Debian has been developed openly and distributed freely according to some of the principles of the GNU Project and Free Software. Because of this, the Free Software Foundation sponsored the project from November 1994 to November 1995. However, Debian ...
