注解

标准打印机通常通过打印第一个副本的每一页，然后打印第二个副本的每一页，等等来整理输出。 当标准打印机不进行排序时，它会打印第一页的每一份副本，然后打印第二页的每份副本，依此打印。

一些打印机专门配备了整理箱。这些特别配备的打印机的打印顺序可能与标准打印机的打印顺序不同：但是，结果相同：多页打印作业的每个副本都包含其按正确顺序排列的所有页面，而无需手动排序。

此类型的值主要用于以下目的。

• 作为 集合的成员 CollationCapability （是 的 PrintCapabilities属性），这些值指示打印机支持的输出类型。 (许多打印机都支持这两种类型。)

• 作为 的 属性的值CollationPrintTicket，该值指示打印机是否进行排序。

未知值永远不会在 对象的属性PrintCapabilities中使用。

切勿将 PrintTicket 属性设置为 Unknown。 如果其他 PrintTicket 某个生成应用程序已创建 一个 PrintTicket 文档 ，该文档将排序规则功能设置为无法识别的排序规则选项，则 PrintTicket 应用程序中使用该文档构造的对象将具有 未知 作为 属性的值 Collation 。

PrintTicket尽管 无法继承 和 PrintCapabilities 类，但可以扩展打印架构，以识别 在 或 PrintCapabilities 类中PrintTicket未考虑的打印设备功能。 有关详细信息，请参阅 如何：扩展打印架构和创建新的打印系统类。
