How can I create an option in the print PDF pop up menu with Automator?
Simply putting an Alias to the application in the Library/PDF Services folder (either the User's Library folder or the root level /Library folder) should be sufficient to send the PDF from the print menu's &quot;Save As PDF&quot; button to any application.
This should have the same effect as opening the document with the app, or dropping it on the app's icon. It may depend what the app does with incoming documents.
