ADF 11G : How to Implement Print functionality in ADF?

APPROACH-1

    public void beforePhaseMethod(PhaseEvent phaseEvent) {
      //only perform action if RENDER_RESPONSE phase is reached
      if (phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE){
        FacesContext fctx = FacesContext.getCurrentInstance();
        //check internal request parameter
        Map requestMap = fctx.getExternalContext().getRequestMap();
        Object showPrintableBehavior =                  
     requestMap.get("oracle.adfinternal.view.faces.el.PrintablePage");           
        if(showPrintableBehavior != null){
          if (Boolean.TRUE == showPrintableBehavior){
             ExtendedRenderKitService erks = null;
             erks = Service.getRenderKitService(
                               fctx,ExtendedRenderKitService.class);
             //invoke JavaScript from the server
             erks.addScript(fctx, "window.print();");
          }
        }           
      }
    }

APPROACH-2
Just call the window.print() 

    public String print() {
        // Add event code here...
        FacesContext facesContext = FacesContext.getCurrentInstance();

               org.apache.myfaces.trinidad.render.ExtendedRenderKitService service =
                   org.apache.myfaces.trinidad.util.Service.getRenderKitService(facesContext, ExtendedRenderKitService.class);

               service.addScript(facesContext, "window.print();");
        return null;
    }
