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 print; lpq — shows the current print queue
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.
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 names of the lp and lpr commands in Unix were derived from the term "line printer". Analogously, many other systems call their printing devices "LP", "LPT", or some similar variant, whether these devices are in fact line printers or other types of printers.
LPRng is an open-source printing system compatible with the Berkeley printing system and implemented by many open-source Unix-like operating systems. It provides printer spooling and network print server functionality using the Line Printer Daemon protocol.

Printer Command Language, more commonly referred to as PCL, is a page description language (PDL) developed by Hewlett-Packard as a printer protocol and has become a de facto industry standard. Originally developed for early inkjet printers in 1984, PCL has been released in varying levels for thermal , matrix , and page printers.
These are called immediate commands. The second set of commands send data to be printed on the current line plus a paper movement instruction to the printer. Note that in contrast to the ASA control characters, the IBM machine print control characters ask the printer to firstly print the data on the current line, and then secondly advance the ...
