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.
In computers, a printer driver or a print processor is a piece of software on a computer that converts the data to be printed to a format that a printer can understand. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model.
In computer networking, a print server, or printer server, is a type of server that connects printers to client computers over a network. [1] It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle.
A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
Many MFP types, regardless of the category they fall into, also come in a "printer only" variety, which is the same model without the scanner unit included. This can even occur with devices where the scanner unit physically appears highly integrated into the product. As of 2013, almost all printer manufacturers offer multifunction printers ...
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.
In computing, a printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. [1] While most output is human-readable, ...
The solution was to create a queue (or "spool") of documents to be printed and use a daemon (system process) to manage this queue and send the documents to the printer in the order in which they arrived. Such a system, with an lp command to send documents to the queue, was first introduced in 1973 in Version 4 of Unix. [2]
