PageOrder Enum

Definition

指定打印设备是从前往后还是从后往前打印多页文档。Specifies whether a print device prints multi-page documents from front-to-back or back-to-front.

public enum class PageOrder
public enum PageOrder
type PageOrder = 
Public Enum PageOrder
Inheritance
PageOrder

Fields

Reverse 2

以从后往前的顺序输出打印。Output prints in back-to-front order.

Standard 1

以从前往后的顺序输出打印。Output prints in front-to-back order.

Unknown 0

该功能(其选项由此枚举表示)设置为未在打印架构中定义的选项。The feature (whose options are represented by this enumeration) is set to an option not defined in the Print Schema.

Examples

下面的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。The following example shows how to test a printer's capabilities and configure the print job to take advantage of them.

Remarks

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(PrintCapabilities的属性),这些值指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 PrintTicketPageOrder 属性的值,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.

未知值从不用于 PrintCapabilities 对象的属性。The Unknown value is never used in properties of PrintCapabilities objects.

永远不要将 PrintTicket 属性设置为 "未知"。You should never set a PrintTicket property to Unknown. 如果生成应用程序的其他 PrintTicket 创建的PrintTicket 文档将 "页面顺序" 功能设置为无法识别的选项(即,未在打印架构中定义的选项),则应用程序中用该文档构造的 PrintTicket 对象将作为 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.

尽管不能继承 PrintTicketPrintCapabilities 类,但您可以扩展打印架构来识别在 PrintTicketPrintCapabilities 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,请参阅如何:扩展打印架构和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.
