我的打印代码如下所示

void SaveReport(Telerik.Reporting.Report report, string fileName)
{
    ReportProcessor reportProcessor = new ReportProcessor();
    Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();
    instanceReportSource.ReportDocument = report;
    RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);

    using (FileStream fs = new FileStream(fileName, FileMode.Create))
    {
        fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
    }

    // initialize PrintDocument object
    PrintDocument doc = new PrintDocument()
    {
        PrinterSettings = new PrinterSettings()
        {
            // set the printer to 'Microsoft Print to PDF'
            PrinterName = "Canon LBP3000",

            // tell the object this document will print to file
            // PrintToFile = true,

            // set the filename to whatever you like (full path)
            PrintFileName = fileName,
        }
    };
    doc.DocumentName = "My";
    doc.Print();
}

然后我调用函数

SaveReport(new ThermalPrint(), Server.MapPath(@"~\Report\123.pdf"));

该函数执行时没有错误,但打印机不打印pdf文件。 打印机打印对话框就像 enter image description here

我无法理解这个问题。

如果要打印报告,请致电reportProcessor.PrintReport(typeReportSource, printerSettings),但请确保提供有效的PrinterSettings实例。
