What is the difference between network printing via RAW and LPR?

Question

System administration

Explain in a nutshell: "When is it better to use a RAW printer connection, and when LPR."
There is a printer server on Windows 2016. All network printers are connected via IP as usual, i.e. through RAW, but what is the advantage of the LPR protocol?

Answer 1

In short, it makes sense to install LPR on heavily loaded UNIX print servers in order to take advantage of print queues. RAW is more profitable to use with a small print load and the presence of spaced printers (i.e. on a print server). Of course, you can set the protocol that you like more and not delve into the intricacies of the process

Answer 2

RAW is p910nd. Stupid network extension of the printer port.
the printer at the time of printing is captured exclusively.
LPR has castrated queues.
