The Interdependency Browser diagram is compact. Elements of the diagram are moved around to minimize the length of lines connecting the elements. There is no special arrangement to lay the diagram out for printing. As a result, diagram elements might be split between multiple pages.
There are some printer drivers that don't handle the icons in the diagrams very well. If the icons don't appear in the printed diagrams, check the printer's preferences to see if there is a setting that enables the printing of the icons. For example, a printer driver that exhibits the problem has a setting to print in "Raster Mode." Using this Raster Mode results in the icons being printed.
