I need to add a custom form size to the local Print Server through code

I need to add a custom form size to the local Print Server through code. I
would like to do it in a bat file or in C#, or possibly in something else
I can run when running my InstallShield installer.
To better explain, to do this manually, open Devices and Printers and
click on a printer. Then click Print Server Properties. The form below
will open, and you can view/add/delete Forms. I would like to add a new
one here through code (then eventually select this new paper size in the
printers Advanced options).
