Print a Single Page in OneNote
There are actually a couple of answers to do this, depending upon what it is that you actually want to do.
OneNote calls the page tabs along the right side of the screen "pages" so if you actually want to print just a single OneNote Page of a section it's pretty easy. Just go to that page, then click File | Print and make sure that "Current Selection" is selected as you print range. That'll print the current OneNote Page.
If what you want to do is print just one or more specific paper page(s) out of a note that's a little tougher.
To do that, we have a workaround. First you need to print the current OneNote Page (or the entire section if you want) to Adobe Acrobat PDF (or XPS if you want) and then from within Adobe Acrobat select the specific page(s) and print only those paper pages to your printer.
