white gap along top and bottom when printing as PDF

[ryanf6113440]

Hello,

Can someone please tell me why when I am printing as an Adobe PDF I am getting a thin white gap along the top and bottom of each page?

I have added a black rectangle on both master pages which totally fills the page but when I print it shows a white gap along the top and bottom

please refer to the images.

Don't print to PDF. File > Export to PDF. See if that makes a difference.
