A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
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.
Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was ...
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.
Magnetic card stacks were loaded via a reader attached to the left side of the printer and the device could also communicate via BSC or SDLC protocols. The printer for an Office System/6 model 6/440 and 6/450 was an IBM 6640 without a Magnetic Card reader, being instead hard-wired to the 6/440 or 6/450 console for direct printing. [ 7 ]
A personal area network (PAN) is a computer network used for communication among computers and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and video game consoles.
The universal printing dialog box allows users to choose a recently used device, enter a device IP address, search for local print devices, or choose a device from a predefined list. Regardless of the device discovery method used, the Microsoft core driver is updated accordingly and the new device information is then reflected in the normal ...
An original DECwriter is connected to this PDP-11/40 minicomputer. The original DECwriter was introduced in November 1970 at the Fall Joint Computer Conference. [1] [a] Also known by its model number, LA30, it was one of the earliest dot matrix printers to be introduced to market, only months after the seminal Centronics 101 that May at the Spring Joint Computer Conference.
