Question

我在平板电脑上有一个C＃WPF桌面应用程序，该应用程序通过USB电缆连接到打印机。当我尝试从应用程序向该特定打印机打印PDF报告时，出现以下错误：

{System.Printing.PrintQueueException: PrintTicket provider failed to retrieve PrintCapabilities. Win32 error: -2147467259

   at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)}

我知道问题出在此代码行：

{var dialog = new PrintDialog();
pageSize = new Size(dialog.PrintableAreaWidth, dialog.PrintableAreaHeight);}

有什么办法可以解决此问题，因此它适用于所有打印机吗？

谢谢！
