c# - 从 winforms 应用程序打印条形码

Question

我想使用普通打印工具在 winforms 应用程序中打印条形码，而不是通过类似 ZPL 的语言。我可以打印任何不是普通条形码的东西

using (PrintDocument pd = new PrintDocument())
{
    pd.PrintController = new StandardPrintController();
    pd.PrinterSettings.PrinterName = "Printer";
    pd.PrintPage += new PrintPageEventHandler(pd_PrintLabel);
    pd.Print();
}

private void pdPrintLabel(object sender, PrintPageEventArgs ev)
{
    Graphics g = ev.Graphics;

    using (Font f = new Font(FontFamily.GenericSansSerif, 6))
    {
       g.DrawString(????????? what to do for barcode????);
    }
}

Answer 1

我们正在使用条形码渲染框架：

BarcodeDraw bdraw = BarcodeDrawFactory.GetSymbology(BarcodeSymbology.Code128);
Image barcodeImage = bdraw.Draw("barcodetext", barcodeImageHeight);
g.DrawImage(barcodeImage, barcodeRect);

Answer 2

void printDoc()
{

    PrintDocument document = new PrintDocument();
    BarcodeDraw bdraw = BarcodeDrawFactory.GetSymbology(BarcodeSymbology.Code128);
    Image barcodeImage = bdraw.Draw("PO7120172733039800", 50);

    document.PrintPage += delegate(object sender, PrintPageEventArgs e)
    {
        e.Graphics.DrawImage(barcodeImage, 0, 0);
        e.Graphics.DrawString("PO7120172733039800", new Font("arial", 8), new SolidBrush(Color.Black),0,50);
    };
    document.Print();
}

我使用了 Infragistics UltraCode128Barcode1 条形码，它对我有用

  Private Sub btnprintbarcodes_Click(sender As Object, e As EventArgs) Handles btnprintbarcodes.Click

        PrintDocument1.Print()
    End Sub

   Private Sub PrintDocument1_PrintPage(sender As Object, e As PrintPageEventArgs) Handles PrintDocument1.PrintPage
        e.PageSettings.PrinterSettings.PrinterName = ApplicationHelper.GetApplicationSettingValue("Barcode_Printer_Name")
        Dim barcodeImageFile As String = String.Empty
        If UltraCode128Barcode1.Data IsNot Nothing Then
            barcodeImageFile = String.Concat(Path.GetTempPath(), Guid.NewGuid(), ".tiff")
            UltraCode128Barcode1.SaveTo(barcodeImageFile, ImageFormat.Tiff)
            Dim barcodeimage = Image.FromFile(barcodeImageFile)
            e.Graphics.DrawImage(barcodeimage, 0, 0)
            e.Graphics.DrawString(UltraCode128Barcode1.Data, New Font("arial", 8), New SolidBrush(Color.Black), 0, 50)
        End If
        If (File.Exists(barcodeImageFile)) Then
            'File.Delete(barcodeImageFile)
        End If
    End Sub

  Private Sub PrintDocument1_BeginPrint(sender As Object, e As PrintEventArgs) Handles PrintDocument1.BeginPrint
        ApplicationHelper.ShowGeneralDialog("The Program is about to print barcode(s).Make sure your barcode printer is on and loaded")
    End Sub
