    The Desktop API in AWT uses the native functionality of the system (in this case Windows.) The JVM is likely invoking ShellExecute/ShellExecuteEx on the file with the “print” command. The way Windows handles the command is to search the registry for the file type’s print command, and run that. For most file types, this will result in the application that handles it opening, and then executing the print command automatically.

    In short, I don’t think you’ll be able to use the Desktop API without having the applications open. You would need to do all the printing yourself (which, of course, is very difficult.)
