My notes, things I have learned, and documentation I have created.

To setup a network printer that is created and shared on SERVERNAME:

RUNDLL32.EXE printui.dll,PrintUIEntry /in /n\\SERVERNAME\PRINTERSHARENAME

To set that printer as the default printer:

RUNDLL32.EXE printui.dll,PrintUIEntry /y /n\\SERVERNAME\PRINTERSHARENAME

This can be useful to help somebody get a printer connected easily using a script.
