示例

以下示例演示如何测试打印机的功能，以及如何配置打印作业以利用这些功能。

注解

使用此类型的值主要用于以下目的：

作为集合的成员 PagesPerSheetDirectionCapability （它是的 PrintCapabilities属性），这些值指示打印机支持的页面排列方式。
作为的属性PrintTicket的值PagesPerSheetDirection，值指示打印机按指定方向排列内容页。

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 一些生成应用程序创建了 PrintTicket 文档 ，该文档将每张页方向功能设置为无法识别的选项， (即打印架构) 中未定义的选项，则 PrintTicket 应用程序中使用该文档构造的对象将具有 Unknown 作为属性的值 PagesPerSheetDirection 。

PrintTicket尽管无法继承和 PrintCapabilities 类，但你可以扩展打印架构以识别未在或 PrintCapabilities 类中PrintTicket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。
