I am not sure why it isn't working for you Roy.
My experience has always been that you can see any text added to the Vital sign note section in the print preview and the actual hard copy. You cannot see it in the electronic portion of Vital Signs only, but it does show up in the print preview and you can see it in the printed document.
In fact, I have tried to change this forever and do not allow anyone to enter any text there, because when I print out the weights and heights, etc., the VS note always overlaps the HC.
