Printing to PDF on OS X

[Mark Smith]

Can anyone tell me how I can print 1 card to a pdf. The following 
produced a pdf ok, but it was blank...

on printMe
   open printing with dialog
   if the result is "Cancel" then exit printme
   print cd 1 of this stack
   close printing
end print me

if I choose the "Print" option when the dialog appears, the printer 
prints the card, but if I choose the "save as pdf option" and "Save", 
the pdf is created, but it does not have any content.

I'm stumped.

Thanks,

Mark Smith
