How to data binding ADO.NET DataSet XML to print barcode labels with Zebra ZPL printers and VB.NET or C# by using ThermalLabel SDK for .NET

Prerequisites
– Neodynamic ThermalLabel SDK for .NET
– Microsoft .NET Framework 2.0 (or greater)
– Microsoft Visual Studio 2005 / 2008
– Microsoft Visual Studio 2005 / 2008 Express Editions (VB, C#, J#, and C++)
– Any Zebra Thermal Printer supporting ZPL (Zebra Programming Language)

ThermalLabel SDK supports .NET Data Binding scenarios allowing you to print thermal labels bound to a data source such as custom .NET objects, XML files, Databases, ADO.NET, etc.

In this guide you will learn how to perform data binding with XML files to print barcode labels with Zebra ZPL printers by using ThermalLabel SDK for .NET

The following sample features a XML file containing books info. An ADO.NET DataSet object wrapping the books info from the XML source and a ThermalLabel objects will be used to perform data binding scenario printing a set of thermal labels for each book.

IMPORTANT: To test the sample code you must have installed a Zebra ZPL thermal printer.

Follow these steps:
– Download and install latest version of Neodynamic ThermalLabel SDK for .NET
– Open Visual Studio 2005 / 2008 and create a Windows Forms application.
– Add a reference to Neodynamic.SDK.ThermalLabel.dll assembly.
– Create a XML File in C:\temp\books.xml with the following content:


<Books xmlns="">
<Book ISBN="0-7356-0562-9" Title="XML in Action" />
<Book ISBN="0-7356-1377-X" Title="Introducing Microsoft .NET" />
<Book ISBN="0-7356-1288-9" Title="Inside C#" />
<Book ISBN="0-7356-1370-2" Title="Programming Microsoft Windows With C#" />
<Book ISBN="0-7356-1448-2" Title="Microsoft C# Language Specifications" />
<Books />

– Add a button control onto the form and paste the following code in the click event handler of the button:

Visual Basic .NET


//'Define a ThermalLabel object and set unit to cm and label size
Dim tLabel As New ThermalLabel(UnitType.Cm, 6, 4)
'TextItem for ISBN Text...
Dim txt1 As New TextItem(0.75, 0.5, "")
//'set font...
txt1.Font.Name = "0"
txt1.Font.CharHeight = 12
'set text...
txt1.Text = "ISBN:"

// ‘TextItem for ISBN data field…
Dim txt2 As New TextItem(2, 0.5, “”)
‘set font…
txt2.Font.Name = “0”
txt2.Font.CharHeight = 10
‘set Data Source field…
txt2.DataField = “ISBN”

// ‘BarcodeItem for encoding ISBN data field…
Dim bc As New BarcodeItem(1.25, 1.3, BarcodeSymbology.Isbn, “”)
// ‘Set Data Source field…
bc.DataField = “ISBN”
// ‘Set barcode dimensions
bc.BarHeight = 2
bc.BarWidth = 0.04

//’Add items to ThermalLabel object…
tLabel.Items.Add(txt1)
tLabel.Items.Add(txt2)
tLabel.Items.Add(bc)

//’Create data source…
Dim books As New DataSet()
books.ReadXml(“c:\temp\books.xml”)

//’set data source…
tLabel.DataSource = books.Tables(“Book”)

// ‘Create a PrintJob object
Dim pj As New PrintJob()
// ‘Thermal Printer is connected through USB
pj.PrinterSettings.Communication.CommunicationType = CommunicationType.USB
// ‘Set Thermal Printer resolution
pj.PrinterSettings.Dpi = 203
// ‘Set Thermal Printer name
pj.PrinterSettings.PrinterName = “Zebra TLP2844-Z”
// ‘Print ThermalLabel object…
pj.Print(tLabel)

Visual C# .NET


// Define a ThermalLabel object and set unit to cm and label size
ThermalLabel tLabel = new ThermalLabel(UnitType.Cm, 6, 4);

// TextItem for ISBN Text…
TextItem txt1 = new TextItem(0.75, 0.5, “”);
//set font…
txt1.Font.Name = “0”;
txt1.Font.CharHeight = 12;
//set text…
txt1.Text = “ISBN:”;

//TextItem for ISBN data field…
TextItem txt2 = new TextItem(2, 0.5, “”);
//set font…
txt2.Font.Name = “0”;
txt2.Font.CharHeight = 10;
//set Data Source field…
txt2.DataField = “ISBN\”;

//BarcodeItem for encoding ISBN data field…
BarcodeItem bc = new BarcodeItem(1.25, 1.3, BarcodeSymbology.Isbn, “”);
//Set Data Source field…
bc.DataField = “ISBN”;
//Set barcode dimensions
bc.BarHeight = 2;

bc.BarWidth = 0.04;

//Add items to ThermalLabel object…
tLabel.Items.Add(txt1);
tLabel.Items.Add(txt2);
tLabel.Items.Add(bc);

//Create data source…
DataSet books = new DataSet();
books.ReadXml(@”c:\temp\books.xml\”);

//set data source…
tLabel.DataSource = books.Tables[“Book”];

//Create a PrintJob object
PrintJob pj = new PrintJob();
//Thermal Printer is connected through USB
pj.PrinterSettings.Communication.CommunicationType = CommunicationType.USB;
//Set Thermal Printer resolution
pj.PrinterSettings.Dpi = 203;
//Set Thermal Printer name
pj.PrinterSettings.PrinterName = “Zebra TLP2844-Z”;
//Print ThermalLabel object…
pj.Print(tLabel);

– Run the sample Windows Forms application and test it.
