C# System.Drawing.Printing:RPC服务器不可用

我正在运行一些非常基本的打印代码：（使用.NET4.0，VS2012，Windows8）

它抛出了一个错误：

System.ComponentModel.Win32Exception was unhandled

这确实是一个很长的机会，但我认为您应该检查您是否正在打印到您认为要打印到的打印机……）

（检查您是否正在打印到正确的打印机，并且打印机已打开）

System.Drawing.printing和Windows printing api都不使用RPC。您需要首先签出打印机驱动程序。System.Drawing.Printing和Windows Printing api都不使用RPC。您需要先查看打印机驱动程序。实际上，您的评论很有帮助！！错误突然消失了！“默认打印机”当时未连接到我的电脑。。。。仍然不知道为什么会发生错误，但现在，至少问题消失了。：）谢谢说实话，这“真的”不是一个很长的机会……）您正在尝试打印，在这种情况下，只有您的打印机驱动程序试图将命令发送到服务器（打印机），这可能不可用。。“Message=RPC服务器不可用”对于我来说，重新启动后台打印程序服务解决了问题+1-这个答案是解决此类问题的良好起点。在我的例子中，我试图从运行在未连接到域的VM上的.NET应用程序进行打印，因此我猜我没有通过试图打印到的服务器的身份验证。使用windows资源管理器访问上述服务器时，提示我输入凭据，一旦缓存，.NET应用程序就可以进行打印。这是一条毫无帮助的错误消息！实际上你的评论很有帮助！！错误突然消失了！“默认打印机”当时未连接到我的电脑。。。。仍然不知道为什么会发生错误，但现在，至少问题消失了。：）谢谢说实话，这“真的”不是一个很长的机会……）您正在尝试打印，在这种情况下，只有您的打印机驱动程序试图将命令发送到服务器（打印机），这可能不可用。。“Message=RPC服务器不可用”对于我来说，重新启动后台打印程序服务解决了问题+1-这个答案是解决此类问题的良好起点。在我的例子中，我试图从运行在未连接到域的VM上的.NET应用程序进行打印，因此我猜我没有通过试图打印到的服务器的身份验证。使用windows资源管理器访问上述服务器时，提示我输入凭据，一旦缓存，.NET应用程序就可以进行打印。这是一条毫无帮助的错误消息！
