使用C＃更改打印机驱动打印属性设置
|
更多源码参考，可参考本人csdn下载空间(http://download.csdn.net/detail/kingmax54212008/9881707)。或联系本人：[email protected] 介绍为应用程序打印MS Word文档，并且应该给用户一个选项来更改他/她想要打印的文档的打印机设置，以便用户可以更改打印机的页面源和双面打印属性。 当我们开始将代码转换为C＃时，我发现MS Word API中没有功能来更改打印机的双面打印属性。Word在WordApplication类' PrintOut方法中提供了一个参数，但是Microsoft建议不要使用它，因为它是操作系统和语言相关的。 真正令人担忧的是.NET中的打印库。我没有找到任何可以更改打印机设置的类PrintDocument与它相关联。我真的觉得.NET应该提供类来更改打印机设置，或者为此，.NET应该提供了一个库，它有助于防止开发人员使用依赖于操作系统的WIN API（最终在设计打印机类中这是OS独立的）。 另一个问题是，OpenPrinter不适用于网络打印机（虽然Microsoft建议设置打印机的方式，我不能对客户端做同样的事情）。有趣的部分是VB6代码没有任何问题（访问被拒绝）工作，所有MS Office工具都可以正常工作，那为什么不是C＃代码？ 以下是全局更改打印机设置的C＃代码。这只是一个示例代码。请原谅我，因为代码不是优雅的，唯一的意图是解释它是如何工作的。代码不适用于网络打印机。有关设置网络打印机的更多信息，请参阅以下链接。 MSDN 隐藏 收缩
