One of the new features added in OneNote 2010 is the ability to manage DRM (Digital Rights Management) protected documents.  DRM is a technology that allows the author of a document to limit who can view the content in their document.  This is a great step forward for privacy.  OneNote now keeps track of the entire collection of pages inserted as a printout on your OneNote page.  However, this also means that once a page is removed from the collection, OneNote detects that the page(s) are missing and displays the following message:

One or more pages in the Printout below are hidden.  To remove this message, delete all pages of the Printout below.

This doesn’t actually affect the Printout Manager unless you decide to split the printout pages onto separate OneNote pages.  Once that happens, OneNote will recognize that some of the pages are missing and display the above message.  It doesn’t prevent or break anything, it’s just more of an annoyance than anything else.

OneNote Printout Manager

To use the OneNote Printout Manager, simply download the file at the bottom of this blog post onto your computer.  It contains installation files for both 64-bit and 32-bit versions of OneNote.  Install the most appropriate one for your particular installation of Office.  Once you have the OneNote Printout Manager installed, click Insert –> Printout Manager and you’re set to go.
