我有一个要打印 Word 文档的应用程序。我正在使用第三方 GemBox 软件,并且在我的开发环境中此代码有效;
public void OutputLetter(string outputFile, string placeholder, string newText)
{
using (var document = DocX.Load(this.InputFile))
{
document.ReplaceText(placeholder, newText);
document.SaveAs(outputFile);
}
this.PrintDocument(outputFile);
}
private void PrintDocument(string outputFile)
{
var document = DocumentModel.Load(outputFile, LoadOptions.DocxDefault);
document.Print(AppSettings.PrinterName);
}
AppSettings.PrinterName 是存储在 web.config 中的打印机的名称。一旦我部署它,我就会在线得到这个错误;“document.Print(AppSettings.PrinterName);”
System.Printing.PrintQueueException: PrintTicket provider failed to bind to printer. Win32 error: Access is denied.
在我得到的事件查看器上;
The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{BA7C0D29-81CA-4901-B450-634E20BB8C34}
and APPID
{AA0B85DA-FDDF-4272-8D1D-FF9B966D75B0}
to the user IIS APPPOOL\Mulalley SID (S-1-5-82-1744840036-3971326342-2272496405-1389653927-2904033151) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.
我该如何解决?
