I have a number of networked printers setup using Print Management under Windows Server 2008 R2 and a few of them have multiple port names for the same IP address.
eg.
Ground Floor Printer GROUNDFLOOR (Standard TCP/IP Port)
IP: 123.123.123.123
Port Name: 123.123.123.123
Port Name: 123.123.123.123_1
Port Name: 123.123.123.123_2 GROUNDFLOOR
Can anyone explain this sort of behaviour?

Someone or something tried to create a new TCP/IP port at the same IP address as an existing port. Port names need to be unique, so the new port couldn't share the same name with the existing port. By default, Windows Print Server will append an underscore and a number (
_1, then_2, then_3, etc.) to the port name to satisfy the unique name requirement for ports.
