This is a regression. When diagrams are printed, they use the default preferences hint and mapping mode instead of the one that is supplied in the contructor for DiagramPrinter. The following code in DiagramPrinter#run() seems to be the problem:

-------------------------------------------
DiagramEditPart dgrmEP = PrintHelper.createDiagramEditPart((Diagram) obj, null);
            
RootEditPart rep = dgrmEP.getRoot();
if (rep instanceof DiagramRootEditPart) 
    this.mm = ((DiagramRootEditPart)rep).getMapMode();
if (rep instanceof IDiagramPreferenceSupport)
    this.preferencesHint = ((IDiagramPreferenceSupport)rep).getPreferencesHint();
-------------------------------------------

This code assumes that the OffscreenEditPartFactory has obtained the correct preferences hint and mapping mode, when in effect it uses the default ones. The fix:

-------------------------------------------
DiagramEditPart dgrmEP = PrintHelper.createDiagramEditPart((Diagram) obj, preferencesHint);
-------------------------------------------

The reason for this goes back to trying to get all open GMF diagrams in list in the print dialog...since different _types_ of diagrams will have different preferences. See bug 144771.

Even after this fix, the Bug 160696 needs to be looked into.
