Remarques

Si la première PrintTicket demande à l’impression de fonctionnalités que l’imprimante ne prend pas en charge, le pilote d’imprimante résout tous les conflits afin de produire un ticket viable.If the initial PrintTicket asks for printing functionality that the printer does not support, the printer driver resolves all conflicts in order to produce a viable ticket.
