    Prerequisites
    - Neodynamic Barcode Professional 6.0 for Windows Forms (WinControl)
    - Microsoft .NET Framework (any version)
    - Microsoft Visual Studio .NET (any version) or Microsoft Visual Basic Express or Visual C# Express Editions

    In this guide you will learn how to print images or pictures, texts and barcodes by using Barcode Professional and .NET PrintDocument class.

    - Open Visual Studio and create a new Windows Forms app using your preferred .NET language VB or C#
    - In your project add a reference to Neodynamic.WinControls.BarcodeProfessional.dll
    - Open the default form in design view and drag & drop a Button control, a PrintDialog and PrintDocument components from VS toolbox
    - Double-click on the Button control and paste the following code inside the button's Click event handler
    Visual Basic .NET
    'show print dialog...
    If printDialog1.ShowDialog() = DialogResult.OK Then
    'set printer settings on printdocument object
    printDocument1.PrinterSettings = printDialog1.PrinterSettings
    'print...
    printDocument1.Print()
    End If

    Visual C# .NET
    //show print dialog...
    if (printDialog1.ShowDialog() == DialogResult.OK)
    {
    //set printer settings on printdocument object
    printDocument1.PrinterSettings = printDialog1.PrinterSettings;
    //print...
    printDocument1.Print();
    }

    - Back to the form design view and now double-click on the PrintDocument component. In the code behind class, paste the following code inside the PrintDocument's PrintPage event handler
    Visual Basic .NET
    'printing barcode coupon...

    '1. Print the company logo and % for coupon...
    Dim logo As Image = Image.FromFile(@"C:\temp\AWCoupon.jpg")
    e.Graphics.DrawImage(logo, New Point(0, 0))
    logo.Dispose()

    '2. Print barcode...
    Dim barcode As New Neodynamic.WinControls.BarcodeProfessional.BarcodeProfessional()

    'set barcode symbology... eg Code 128
    barcode.Symbology = Neodynamic.WinControls.BarcodeProfessional.Symbology.Code128
    'set barcode bars dimensions...
    barcode.BarcodeUnit = Neodynamic.WinControls.BarcodeProfessional.BarcodeUnit.Inch
    barcode.BarWidth = 0.015
    barcode.BarHeight = 0.75
    'set value to encode... this time a random value...
    barcode.Code = Guid.NewGuid().ToString().ToUpper().Substring(0, 16)
    'justify text...
    barcode.CodeAlignment = Neodynamic.WinControls.BarcodeProfessional.Alignment.BelowJustify
    'set font for barcode human readable text...
    Dim fnt As New Font("Courier New", 10F)
    barcode.Font = fnt
    fnt.Dispose()
    'print barcode below logo...
    'IMPORTANT: barcode location unit depends on BarcodeUnit setting which in this case is INCH
    barcode.DrawOnCanvas(e.Graphics, New PointF(0.1F, 1.5F))

    '3. Print some texts...
    Dim fnt1 As New Font("Arial", 12F, FontStyle.Bold)
    Dim fnt2 As New Font("Arial", 8F, FontStyle.Regular)

    e.Graphics.DrawString("RESELLER INTRUCTIONS", fnt1, Brushes.Black, New PointF(10F, 270F))
    e.Graphics.DrawString("Use Item -% Off for the 15%. Scan coupon barcode or enter coupon code. Collect coupon with purchase as coupon may only be redeemed once per customer.", fnt2, Brushes.Black, New RectangleF(New PointF(10F, 290F), New SizeF(570F, 50F)))

    e.Graphics.DrawString("COUPON OFFER DETAILS", fnt1, Brushes.Black, New PointF(10F, 350F))
    e.Graphics.DrawString("This coupon can be redeemed once at any Adventure Works Cycles retail store." + Environment.NewLine + "This coupon is valid from May 21, 2009 to Jun 21, 2009.", fnt2, Brushes.Black, New RectangleF(New PointF(10F, 370F), New SizeF(570F, 50F)))

    fnt1.Dispose()
    fnt2.Dispose()

    Visual C# .NET
    //printing barcode coupon...

    //1. Print the company logo and % for coupon...
    using (Image logo = Image.FromFile(@"C:\temp\AWCoupon.jpg"))
    {

    }

    using (Neodynamic.WinControls.BarcodeProfessional.BarcodeProfessional barcode = new Neodynamic.WinControls.BarcodeProfessional.BarcodeProfessional())
    {
    //set barcode symbology... eg Code 128
    barcode.Symbology = Neodynamic.WinControls.BarcodeProfessional.Symbology.Code128;

    barcode.DrawOnCanvas(e.Graphics, new PointF(0.1f, 1.5f));
    }

    //3. Print some texts...
    using (Font fnt1 = new Font("Arial", 12f, FontStyle.Bold))
    {
    using (Font fnt2 = new Font("Arial", 8f, FontStyle.Regular))
    {
    e.Graphics.DrawString("RESELLER INTRUCTIONS", fnt1, Brushes.Black, new PointF(10f, 270f));
    e.Graphics.DrawString("Use Item -% Off for the 15%. Scan coupon barcode or enter coupon code. Collect coupon with purchase as coupon may only be redeemed once per customer.", fnt2, Brushes.Black, new RectangleF(new PointF(10f, 290f), new SizeF(570f, 50f)));

    e.Graphics.DrawString("COUPON OFFER DETAILS", fnt1, Brushes.Black, new PointF(10f, 350f));
    e.Graphics.DrawString("This coupon can be redeemed once at any Adventure Works Cycles retail store." + Environment.NewLine + "This coupon is valid from May 21, 2009 to Jun 21, 2009.", fnt2, Brushes.Black, new RectangleF(new PointF(10f, 370f), new SizeF(570f, 50f)));
    }
    }

    Re: How to print images, pictures, texts and high quality barcodes using VB.NET or C#

    Is this neodynamic .net barcode generator compatible with ASP.NET web application? I have a task which requires me to finish this job at web-side server.

    I found this when I was engaged in my project with barcode generating and reading.It provides C# and also VB.NET solution.And what impressed me most is that the provider of the library offers excellent service for an 100% free product.You can even request customized demo from their support forum.Hope it helps.
