Thank you Paul for your help !
But the page size is OK. For those who may have the same trouble, I found the reason.
In the "Print Setup" dialog box we have to Print TrueType fonts as graphics.
If the driver doesn't allow the user to change this value with the dialog box, we can change it by
soft, by overriding CView::OnPreparePrinting, and acting directly on the structure LPDEVMODE
stored in the CPrintInfo class. After getting the pointer to this structure we have to write
something like :

lpDevMode->dmTTOption=DMTT_BITMAP;
