Deploying Printers using GP Preferences - Network Printer and Local LPTx ports - Why local port for a remote shared printer?

I´m trying to create in user´s PCs printers (print queues) and i´m trying to configure using GP Preferences, insted Deploy Printers (old method). All printers are shared in a dedicated print server as \\server\printerX  in the GPP screen, i have to type the printer name and the printer path (\\server\printer$), that´s OK.

But a mandatory parameter is the port (LPT1 for example)

It will be ignored?
