You can use the Print Preview settings of the browsers to customize the zoom level of the org chart so it fits on a sheet of paper. You could also tweak the orientation of the page portrait if the org chart is tall or landscape if the orgchart is wide.
In addition, you could tweak the styles of the org chart items to make them smaller.
Of course all that is performed on a per case basis and it would be nice to see that org chart before giving you a more concrete example.
