How to get Private Notes on a Custom Invoice

I created a custom invoice that I use to print out for record - it is not the one I send to the customer. On this custom invoice I included areas for me to put in our cost and shipping so that I can figure out profit margins. I also need to display the private notes section on this special invoice. So that we can put in customer info that we want documented on the invoice that goes in the file.

Help please not sure how to get the private notes on the invoice.
