定义

命名空间:

System.Printing

程序集:

ReachFramework.dll

指定用作空白纸或其他打印介质源的送纸盒。

public enum class InputBin

public enum InputBin

type InputBin = 

Public Enum InputBin

继承

Object

ValueType

Enum

InputBin

字段

AutoSelect	1	根据纸张大小和介质输出类型自动选择送纸盒。
AutoSheetFeeder	4	使用自动送纸盒。
Cassette	2	使用可移动的送纸盒。
Manual	5	使用手动送纸盒。

示例

以下示例演示如何确定打印机功能并配置打印作业以利用它们。

注解

此类型的值主要用于以下目的：

• 作为集合的成员 InputBinCapability （属性 PrintCapabilities），它们指示打印机支持的输入箱的类型。

• 作为属性PrintTicket的值InputBin，它们指示打印机使用指定的箱。

该值 Unknown 永远不会用于对象的属性 PrintCapabilities 。

不应将 PrintTicket 属性设置为 Unknown. 如果其他 PrintTicket 一些生成应用程序创建了一个 PrintTicket 文档，该文档将输入箱功能设置为无法识别的 optio， (即打印 架构中未定义的选项，则 PrintTicket 使用该文档构造的应用程序中的对象将具有 Unknown 该属性的值 InputBin 。

PrintTicket虽然无法继承这些和PrintCapabilities类，但你可以扩展打印架构，以识别不在或PrintCapabilities类中PrintTicket考虑的打印设备功能。 有关详细信息，请参阅 如何：扩展打印架构并创建新的打印系统类。
