Running scripts from Finder, and printing without a dialog

Question

Two questions:
1. I need to launch an InDesign script from outside of InDesign -- such as launching the script from the finder (Mac) and having it run in InDesign. How can I do this?
2. How can I script printing a document so that it automatically prints, bypassing the Print dialog box that a user would need to click on (I want it to print automatically in the background without the user doing anything)?

Answer 1

1. Just save your script as an application and wrap your stuff in an "on run" statement.
on run
tell application "Adobe InDesign"
--do stuff
end
end
See the Applescript Language Reference at developer.apple.com/applescript for more info.
2. Yup. The "do stuff" in your case will probably look something like this:
tell active document
--Set up options, assumes you have created a printer preset
-- with the output options you want
set active printer preset of print preferences to "my printer preset"
set page range of print preferences to all pages
--And then print
print without print dialog
end
