Question

我有一个c＃dll，它使用HiQPdf从文件中打印PDF。问题是打印的PDF在左上角添加了一个字符串＆＃34; HiQPdf Evaluation＆＃34;。 marigins也大大增加，使图像更小。

当我打开pdf并从那里打印时，它很好。我无法在添加的字符串上找到任何内容，所以希望有人在这里有一些见解：）

代码：

    public void PrintFromFile(string fileName, System.Drawing.Printing.PrinterSettings printerSettings)
    {
        var imagePrinter = new PdfPrinter();
        imagePrinter.PrinterSettings.Copies = printerSettings.Copies;
        imagePrinter.PrinterSettings.Duplex = printerSettings.Duplex;
        imagePrinter.PrinterSettings.FromPage = printerSettings.FromPage;
        imagePrinter.PrinterSettings.MaximumPage = printerSettings.MaximumPage;
        imagePrinter.PrinterSettings.MinimumPage = printerSettings.MinimumPage;
        imagePrinter.PrinterSettings.PrinterName = printerSettings.PrinterName;
        imagePrinter.PrinterSettings.PrintFileName = printerSettings.PrintFileName;
        imagePrinter.PrinterSettings.PrintRange = printerSettings.PrintRange;
        imagePrinter.PrinterSettings.PrintToFile = printerSettings.PrintToFile;
        imagePrinter.PrinterSettings.ToPage = printerSettings.ToPage;
        imagePrinter.PrinterSettings.Collate = printerSettings.Collate;

        var pdf = new MemoryStream(System.IO.File.ReadAllBytes("V:\\AccW2\\" + fileName));
        pdf.Position = 0;
        imagePrinter.PrintPdf(pdf);
    }

如果PrintPdf函数中有HtmlToPdf元素，则应设置SerialNumber

    private void PrintPdf(string htmlbody, string pdfname)
{
    HtmlToPdf htmlToPdfConverter = new HtmlToPdf();
    // set a demo serial number
    htmlToPdfConverter.SerialNumber = "-- HiQPdf Serial Number --";

}

打印时添加了HiQPdf评估标签
