如何使用RDLC报告C＃打印动态纸张高度而无需裁切？

Question

这是我使用的代码：

将数据集和参数设置为RDLC报告

private static int m_currentPageIndex;

report.DataSources.Add（new ReportDataSource（“ dsReceiptInfor”，ReceiptInfor））; ReportParameter [] param = new ReportParameter [2];

param [0] = new ReportParameter（“ imgPath”，FilePath）; param [1] = new ReportParameter（“ BaseCurrencyFormat”，BaseCurrencyFormat）;

report.SetParameters（param）;

导出（报告）;

Print（）;

---

功能

-导出

    private static void Export(LocalReport report)
    {
     string deviceInfo =
          @"<DeviceInfo>
            <OutputFormat>EMF</OutputFormat>
            <PageWidth>8.5in</PageWidth>
            <PageHeight>11in</PageHeight>
            <MarginTop>0in</MarginTop>
            <MarginLeft>0in</MarginLeft>
            <MarginRight>0in</MarginRight>
            <MarginBottom>0in</MarginBottom>
        </DeviceInfo>";
            Warning[] warnings;
            m_streams = new List<Stream>();
            report.Render("Image", deviceInfo, CreateStream, out warnings);

            foreach (Stream stream in m_streams)
                stream.Position = 0;
     }

-打印

    private static void Print()
    {
        if (m_streams == null || m_streams.Count == 0)
            throw new Exception("Error: no stream to print.");

        PrintDocument PrintBill = new PrintDocument();
        PrintBill.PrintPage += new PrintPageEventHandler(PrintPage);
        PrintBill.PrinterSettings.PrinterName = PrinterName;
        PrintBill.PrintController = new StandardPrintController();
        m_currentPageIndex = 0;
        PrintBill.Print();
    }

-PrintPage

    private static void PrintPage(object sender, PrintPageEventArgs ev)
    {
        try
        {
            Metafile pageImage = new Metafile(m_streams[m_currentPageIndex]);

            //Adjust rectangular area with printer margins.
            Rectangle adjustedRect = new Rectangle(
                0,
                0,
                765,
                ev.PageBounds.Height);
            //Draw a white background for the report
            ev.Graphics.FillRectangle(Brushes.White, adjustedRect);


            // Draw the report content
            ev.Graphics.DrawImage(pageImage, adjustedRect);

            // Prepare for the next page. Make sure we haven't hit the end.
            m_currentPageIndex++;
            ev.HasMorePages = (m_currentPageIndex < m_streams.Count);
        }
        catch (Exception ex)
        {

        }

    }

当打印数据（PageHeight> 11英寸）时，它将被剪切。你能告诉我如何打印与纸张一样长的纸张。 感谢您的关注：）

长时间后，我一直在寻找答案，但仍然找不到。所以我找到了一种无需编码的解决方案。 在打印机设置中，我们可以更改打印机首选项：

纸张来源->文档（剪切）。完成
