c# - 系统.绘图.打印 : The RPC server is unavailable

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();

它抛出一个错误:

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

这真的是一个远景 - 但我认为您应该检查您是否正在打印到您认为正在打印到的打印机.. ;)

(检查您是否打印到正确的打印机并且它已打开)
