You can specify the printer path name in a number of ways. For example, to add a printer that has the queue name hornbeam and is attached to a server called melody, you can specify the port as follows:
melody:hornbeam
pcnfsd:\\melody\hornbeam
pcnfs:\\melody\hornbeam
pcnfsd://melody/hornbeam
pcnfs://melody/hornbeam
\\melody\hornbeam
//melody/hornbeam
123.456.78.90:hornbeam (where 123.456.78.90 is the IP address of the server melody)
