Too many names

From the manifacture, the printer has a netbios name, a model number, its
driver's name, its LPD queue name

On the server, the administrator assigns a print queue name and an IP
address.

Please, what name is used for the server's print queue name and what's the
purpose of it.
On the other hand, why do we need the LPD queue name if we send the print
job to printer's IP address?

Lately, printers manufactures allow any remote queue name for LPD queue name
.... how does that work compare to the specific LPD queues names?

Thanks in advance!
