If you want don't use editors, I guess you have to use Draw2D directly. Here
is an example:
public class ConnectionSnippet {
public static void main( String[] args ) {
Display d = new Display();
Shell shell = new Shell( d );
shell.setLayout( new FillLayout() );
FigureCanvas canvas = new FigureCanvas( shell );
Figure connectionPanel = new Figure();
RectangleFigure node1 = new RectangleFigure(), node2 = new
RectangleFigure();
node1.setBackgroundColor( ColorConstants.red );
node1.setOutline( false );
node1.setBounds( new Rectangle( 40, 40, 50, 30 ) );
node2.setBackgroundColor( ColorConstants.blue );
node2.setOutline( false );
node2.setBounds( new Rectangle( 100, 140, 50, 30 ) );
PolylineConnection conn = new PolylineConnection();
conn.setSourceAnchor( new ChopboxAnchor( node2 ) );
conn.setTargetAnchor( new ChopboxAnchor( node1 ) );
connectionPanel.add( node1 );
connectionPanel.add( node2 );
connectionPanel.add( conn );
canvas.setContents( connectionPanel );
shell.open();
while( !shell.isDisposed() )
while( !d.readAndDispatch() )
d.sleep();
}//main()
}//ConnectionSnippet

I believe GMF has some print preview features.
