Page Setup question (Mac)

[Emmett Gray]

Is there any way to specify landscape or portrait mode via scripting? 
HC remembered the page setup for a template. Rev (Media) doesn't 
remember anything about it when it quits, and seems to have only one 
mode possible for all stacks, not a setting for individual stacks. I 
need to print envelopes in portrait mode and all other stacks in 
landscape mode.

I opened a couple of dictionaries in (Apple) Script Editor but didn't 
find anything there.

My workaround for now is to have a global "lastPageSetup" which is 
checked and invokes "answer page setup" if I need to change it. At 
least that saves paper.
