Troubles with printing 2D Texts - strong changes between 2.3 and 2.4 version

I've just do what you said and the result is the same.
I've taken the MFC sample as it is after installing VTK, and have just added this code :

To SampleDoc.h, in public :
vtkLabeledDataMapper	*m_pLabeledDataMapper;
vtkActor2D		*m_pLabelActor;
vtkSphereSource		*m_pSphere;

To SampleDoc.cpp, just before the end of the constructor :
m_pSphere=vtkSphereSource::New();
m_pSphere->SetRadius(1.);
m_pLabeledDataMapper=vtkLabeledDataMapper::New();
m_pLabeledDataMapper->SetLabelFormat("%ld");
m_pLabeledDataMapper->SetLabelModeToLabelIds();
m_pLabeledDataMapper->SetInput(m_pSphere->GetOutput());
m_pLabelActor=vtkActor2D::New();
m_pLabelActor->SetMapper(m_pLabeledDataMapper);
m_pLabelActor->GetProperty()->SetColor(0.,0.,0.);

To SampleDoc.cpp, in destructor
m_pSphere->Delete();
m_pLabeledDataMapper->Delete();
m_pLabelActor->Delete();

To SampleView.cpp, in CSampleView::OnUpdate :

void CSampleView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint) 
{
 ...
 ...
 this->Renderer->AddProp(GetDocument()->m_pLabelActor);
 this->vtkMFCRenderView::OnUpdate(pSender, lHint, pHint);			
}

I can see all the data as 2D text actors in the window, in fact these values are all set to 0, but
I can't see them in print preview.

thanks a lot again for your help
Hugues
