Unless you're a system administrator using a netorked environment that allows you to disable users' access to those settings (I'm not sure that's possible anyway for those particular settings), you can't really prevent users from changing those settings - they are application-wide, not document-specific.

As a workaround, you could add a Document_Open macro to the template the documents are based on to re-set the setting to 'on' each time one of those documents is opened, and/or an event-driven DocumentBeforePrint macro to do likewise, but users could circumvent those too - whether by accident or intent.
