Script for adding a new printer port type on windows

[SinNisTeR]

I know that I can use prnport.vbs to create a new tcp/ip port, but how do I create a new printer port type? The only way I know how is to manually go into the printer & faxes section, right click on area, go to server properties, click add port, then click new port type.

I'm trying to write a script that'll create a new port type for the xerox wide format printers. Any ideas?

Thanks!
