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.
Note that the LPD queue name is case sensitive. Some modern implementations of LPD on network printers might ignore the case or queue name altogether and send all jobs to the same printer. Others have the option to automatically create a new queue when a print job with a new queue name is received. This helps to simplify the setup of the LPD ...
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.
The Internet Printing Protocol (IPP) is a specialized communication protocol used between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers). The protocol allows clients to submit one or more print jobs to the network-attached printer or print server, and perform tasks such as querying the status of a ...
MPPs are used to control which users have access to device features like color, duplex, etc. By default, HP UPD assumes that the HP MPA is installed on a server named managed-print. As a result, HP UPD searches the network for this server to find HP Managed Print Policies or HP Managed Printer Lists. HP UPD Managed Printer Lists and Print Policies
By installing an HP JetDirect print server card, a LaserJet 4 / 4M printer could be connected to a network, for example as a departmental printer in companies instead of the larger III Si and 4 Si models. In 2020 The New York Times wrote "by the 1990s, it was a staple of offices around the world."
Name services such as mDNS, LLMNR and others do not provide information about the type of device or its status. A user looking for a nearby printer, for instance, might be hindered if the printer was given the name "Bob". Service discovery provides additional information about devices.
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 used to print the document.
