I have been working on a script to print a document that is dropped into a folder. When using a script such as the one in this hint the default page size and settings (defined in printing pref pane) are used. The roadblock I am running into is that the size of my documents are not a standard paper size (20"x27"). Does anyone know how to add a custom page size as the default page size for a printer? You can set the default page size in the printing pref pane, but the only options are standard sizes (The largest being Super B which is 13"x19"). Adding a custom page size in a page setup dialog box does not help.

I'm guessing you would have to edit the Printer Description File (PPD) for that printer and add in that page size. I don't know the syntax for doing such, but poke around and you can probably figure it out.
