How to manage the PageSetup by a script?

[Reinhold Venzl-Schubert]

Hi!

I have a script with a fix height an width of the cards. Therefore I  
only need one adjustment of the margins in the page setup.
What script can set the required margins for me?
This one do not work:

   set the printMargins to 37,35,37,35
   open printing with dialog
   print marked cds
   close printing

Thanks
Reinhold
