one of my Linux OES crashed so I have to replace it. I can't remove iprint
manager and driver store object : through imanager I got the error
"PrintManager Opérateur de suppression:La suppression demandée du type
d'objet iPrintManager a été refusée par un plugin qui dépend de cet objet."
which means in english "PrintManager removal operator : asked removal of
object type iPrintManager was refused by a plugin depending of this object"

Same for driver store. How can I remove those objects from my tree ?
