示例

注解

使用此类型的值主要用于以下目的:Use the values of this type primarily for these purposes:

  • 作为PageOrderCapability集合的成员, 的PrintCapabilities属性为, 这些值表示打印机支持的页面顺序的类型。As members of the PageOrderCapability collection, a property of PrintCapabilities, these values indicate the type of page order that a printer supports. (许多打印机都支持这两种类型。)(Many printers support both types.)

  • 作为的PageOrder属性PrintTicket的值, 该值指示打印机按指定顺序打印输出。As the value of the PageOrder property of a PrintTicket, the value directs a printer to print output in a specified order.

PrintCapabilities对象的属性中从不使用未知值。The Unknown value is never used in properties of PrintCapabilities objects.

永远不应将PrintTicket属性设置为 "未知"。You should never set a PrintTicket property to Unknown. 如果生成应用PrintTicket程序的其他部分创建了一个PrintTicket 文档, 该文档将 "页面顺序" 功能设置为无法识别的选项 (即, 未在打印 PrintTicket架构中定义的选项), 则使用该文档构造的应用程序将作为该PageOrder属性的值未知。If some other PrintTicket producing application has created a PrintTicket document that sets the page order feature to an unrecognized option (that is, an option that is not defined in the Print Schema), then a PrintTicket object in your application that is constructed with that document will have Unknown as the value of the PageOrder property.

PrintTicket PrintCapabilities尽管和PrintTicket PrintCapabilities类不能被继承, 但你可以扩展打印架构来识别在或类中不考虑的打印设备功能。Although the PrintTicket and PrintCapabilities classes cannot be inherited, you can extend the Print Schema to recognize print device features that are not accounted for in the PrintTicket or PrintCapabilities classes. 有关详细信息,请参阅操作说明:扩展打印架构并创建新的打印系统类For more information see How to: Extend the Print Schema and Create New Print System Classes.
