Tab Page setup shifts - Viewports and Drawing border moves

I am taking an existing CAD drawing with many drawing tabs and attempting to use BricsCAD to print the tabs. 

The problem I am having is that the page (white background drawing area) moves / or the drawing border and the viewports all move as well. This seems to occur After I set the drawing to be centered...

I only print to PDF first, and then plot them as pdfs. So is there a way to easy do the following:

1. add a border to all drawings before PDF printing. 

2. Make sure that the drawing can be plotted by windowing the drawing border and ensuring that it does not disturb the drawing once Plotted.
