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 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 printer, obtaining the status of print jobs, or cancelling individual print jobs. Like all IP-based protocols, IPP can run locally or over the Internet.
In addition to illustrating the layout of a network with representative icons for the hosts and interconnecting lines, each device icon may be explored to produce a popup information box summarizing important network and host parameters, such as MAC address and IP address (both IPv4 and IPv6).
Protecting only the services is not enough. Service URLs contain host names or IP addresses, and in a local network it is almost impossible to prevent IP or DNS spoofing. Thus only guaranteeing the authenticity of the URL is not enough if any device can respond to the address.
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.
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.

He found the idea of printer queues not obvious because users create queues on their local computer but these queues are actually created on the CUPS server. He also found the plethora of queue-type options confusing as he could choose from between networked CUPS (IPP), networked Unix ( LPD ), networked Windows ( SMB ), networked Novell ( NCP ...
