Exemples

L’exemple suivant montre comment utiliser cette propriété pour déterminer les fonctionnalités d’une imprimante spécifique et comment configurer un travail d’impression pour en tirer parti.

Remarques

Une imprimante standard rassemble généralement la sortie en imprimant chaque page de la première copie, puis chaque page de la deuxième copie, et ainsi de suite. Lorsqu’une imprimante standard ne s’assemble pas, elle imprime chaque copie de la première page, puis chaque copie de la deuxième page, et ainsi de suite.

Certaines imprimantes sont spécialement équipées de bacs de classement. La séquence d’impression de ces imprimantes spécialement équipées peut différer de celles des imprimantes standard ; Toutefois, le résultat est le même : chaque copie d’un travail d’impression multipage contient toutes ses pages dans l’ordre approprié sans tri manuel.

Si l’imprimante ne prend pas en charge le classement, la collection est vide.

Cette propriété correspond à l’mot clé du DocumentCollateschéma d’impression, et non à la JobCollateAllDocuments mot clé.
