System.Drawing.Printing：RPC服务器不可用

Question

我正在运行一些非常基本的打印代码:(使用.net 4.0，VS 2012，Windows 8）

var bitmap = new Bitmap(control.Width, control.Height);

control.DrawToBitmap(bitmap, new Rectangle(0, 0, control.Width, control.Height));

var pd = new PrintDocument();

pd.PrintPage += (s, e) => e.Graphics.DrawImage(bitmap, 100, 100);
pd.Print();

这是一个错误：

System.ComponentModel.Win32Exception was unhandled
HResult=-2147467259
Message=The RPC server is unavailable

这真的是一个很长的镜头 - 但我认为你应该检查你是否正在打印到你认为要打印的打印机..;）

（检查您是否正在打印到正确的打印机并且已打开）
