Here's the walk-through of LPR printing on the IP protocol.

Note that under "Printer Type" they select "LPD/LPR"
If your printer has an ethernet jack, then the queue name is usually left blank and each printer has its own IP number ("Printer Address"). In the example, they typed a server name under "Printer Address". Chances are, you will be typing in an IP number (192.168.1.78, for example - the number assigned to your printer or to your standalone printserver)
If you're connected through a printserver and it has only one port, generally, the "Queue Name" is left blank (don't write "nil" like they did in the example) and the IP number is that of the printserver.
If you have multiple ports on a printserver, then each port has a name (and the IP number is that of the printserver - same IP number for both ports). Be sure to type the port name into the "Queue Name" field in Print Utility for each printer connected to a port on the printserver.
