    How to print a set of barcode labels in batch using data masking with Zebra ZPL-EPL printers and VB.NET or C# by using ThermalLabel SDK for .NET

    Prerequisites
    - Neodynamic ThermalLabel SDK 2.0 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) or EPL (Eltron Programming Language)

    Data Masking allows you to serialize data items by specifying a Mask string as well as an increment string. Data Masking can be used with TextItem as well as BarcodeItem objects. Data Masking consists of the following concepts:

    - The input Mask string: The mask string must be specified to the Mask property of any TextItem or BarcodeItem objects. The length of the mask string defines the number of characters to be formatted or masked. The mask is aligned to the characters in the target string (i.e. the Text property for TextItem objects or the Code property for BarcodeItem objects) starting with the right-most position. The input mask string must consist of the following characters (a.k.a. Mask String placeholders):

    + D or d (for Decimal numeric 0-9)
    + H or h (for Hexadecimal 09 plus a-f or A-F)
    + O or o (for Octal 07)
    + A or a (for Alphabetic AZ or az)
    + N or n (for Alphanumeric 09 plus AZ or az)
    + % (Ignore character or skip)

    - The Mask Increment string: The mask increment string is the value to be added to the text on each label to be printed and should match the Mask string length. The default value for the increment is equivalent to a decimal value of 1 (one). The string is composed of any characters defined in the input mask string. Invalid characters are assumed to be equal to a value of 0 (zero) in that characters position. The increment value for alphabetic strings start with 'A' or 'a' as the zero placeholder. This means to increment an alphabetic character by one, a value of 'B' or 'b' must be in the increment string. For characters that do not get incremented, the '%' character needs to be added to the increment string.

    In this guide you will learn how to print 10 barcode labels leveraging Data Masking feature with Zebra ZPL or EPL printers by using ThermalLabel SDK for .NET.
    In this sample, each label features a TextItem which will serialize a product model ranging from "MDL-001/X" to "MDL-010/X" (i.e. the sequence will be MDL-001/X, MDL-002/X, MDL-003/X, ..., MDL-010/X) and a BarcodeItem which will serialize a product ID ranging from "PRD000-A" to "PRD900-J" (i.e. the sequence will be "PRD000-A", "PRD100-B", "PRD200-C", ..., "PRD900-J") in Code 128 standard.

    IMPORTANT: To test the sample code you must have installed a Zebra ZPL-based or EPL-based 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 button control onto the form and paste the following code in the click event handler of the button:

    IMPORTANT NOTICE
    Although ThermalLabel SDK supports both ZPL and EPL printers, a label design you write using .NET code like C# or VB.NET will not produce the same output printing under ZPL and EPL printers. If you need to support both printer languages in your project then you will have to design two different labels targeting each printer language separately.

    For ZPL-based Printers
    Visual Basic .NET
    'Define a ThermalLabel object and set unit to cm and label size
    Dim tLabel As New ThermalLabel(UnitType.Cm, 6, 0)

    'Define a TextItem object
    Dim txt As New TextItem(0.5, 0.5, "MDL-001/X")
    'Set font...
    txt.Font.CharHeight = 14
    'set Mask...
    txt.Mask = "%%%%ddd%%"
    txt.MaskIncrement = "1%%"

    'Define a BarcodeItem object
    Dim bc As New BarcodeItem(0.5, 1.5, BarcodeSymbology.Code128, "PRD000-A")
    'Set bars' width and height...
    bc.BarWidth = 0.04
    bc.BarHeight = 2
    'set Mask...
    bc.Mask = "%%%d%%%A"
    bc.MaskIncrement = "1%%%B"

    'Add items to ThermalLabel object...
    tLabel.Items.Add(txt)
    tLabel.Items.Add(bc)

    '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 language
    pj.PrinterSettings.ProgrammingLanguage = ProgrammingLanguage.ZPL
    'Set Thermal Printer name
    pj.PrinterSettings.PrinterName = "Zebra GK420t"
    'Set Copies to 10!!!
    pj.Copies = 10
    '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, 0);

    //Define a TextItem object
    TextItem txt = new TextItem(0.5, 0.5, "MDL-001/X");
    //Set font...
    txt.Font.CharHeight = 14;
    //set Mask...
    txt.Mask = "%%%%ddd%%";
    txt.MaskIncrement = "1%%";

    //Define a BarcodeItem object
    BarcodeItem bc = new BarcodeItem(0.5, 1.5, BarcodeSymbology.Code128, "PRD000-A");
    //Set bars' width and height...
    bc.BarWidth = 0.04;
    bc.BarHeight = 1;
    //set Mask...
    bc.Mask = "%%%d%%%A";
    bc.MaskIncrement = "1%%%B";

    //Add items to ThermalLabel object...
    tLabel.Items.Add(txt);
    tLabel.Items.Add(bc);

    //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 language
    pj.PrinterSettings.ProgrammingLanguage = ProgrammingLanguage.ZPL;
    //Set Thermal Printer name
    pj.PrinterSettings.PrinterName = "Zebra GK420t";
    //Set Copies to 10!!!
    pj.Copies = 10;
    //Print ThermalLabel object...
    pj.Print(tLabel);

    For EPL-based Printers
    Visual Basic .NET
    'Define a ThermalLabel object and set unit to cm and label size
    Dim tLabel As New ThermalLabel(UnitType.Cm, 6, 0)

    'Define a TextItem object
    Dim txt As New TextItem(0.5, 0.5, "MDL-001/X")
    'Set font...
    txt.Font.Name = "2"
    txt.Font.CharHeight = 14
    txt.Font.CharWidth = 8
    'set Mask...
    txt.Mask = "%%%%ddd%%"
    txt.MaskIncrement = "1%%"

    'Define a BarcodeItem object
    Dim bc As New BarcodeItem(0.5, 1.5, BarcodeSymbology.Code128, "PRD000-A")
    'Set bars' width and height...
    bc.BarWidth = 0.04
    bc.BarHeight = 2
    'set Mask...
    bc.Mask = "%%%d%%%A"
    bc.MaskIncrement = "1%%%B"

    'Add items to ThermalLabel object...
    tLabel.Items.Add(txt)
    tLabel.Items.Add(bc)

    '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 language
    pj.PrinterSettings.ProgrammingLanguage = ProgrammingLanguage.EPL
    'Set Thermal Printer name
    pj.PrinterSettings.PrinterName = "Zebra GK420t"
    'Set Copies to 10!!!
    pj.Copies = 10
    '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, 0);

    //Define a TextItem object
    TextItem txt = new TextItem(0.5, 0.5, "MDL-001/X");
    //Set font...
    txt.Font.Name = "2";
    txt.Font.CharHeight = 14;
    txt.Font.CharWidth = 8;
    //set Mask...
    txt.Mask = "%%%%ddd%%";
    txt.MaskIncrement = "1%%";

    //Define a BarcodeItem object
    BarcodeItem bc = new BarcodeItem(0.5, 1.5, BarcodeSymbology.Code128, "PRD000-A");
    //Set bars' width and height...
    bc.BarWidth = 0.04;
    bc.BarHeight = 1;
    //set Mask...
    bc.Mask = "%%%d%%%A";
    bc.MaskIncrement = "1%%%B";

    //Add items to ThermalLabel object...
    tLabel.Items.Add(txt);
    tLabel.Items.Add(bc);

    //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 language
    pj.PrinterSettings.ProgrammingLanguage = ProgrammingLanguage.EPL;
    //Set Thermal Printer name
    pj.PrinterSettings.PrinterName = "Zebra GK420t";
    //Set Copies to 10!!!
    pj.Copies = 10;
    //Print ThermalLabel object...
    pj.Print(tLabel);

    Re: How to print a set of barcode labels in batch using data masking with Zebra ZPL-E

    Hi,

    Great blog, have one quick question though. Personally which would you say is better for the quality and speed of printing barcode labels? I am looking in to starting up myself and need advising.

    Many Thanks
