Create, Preview & Print Barcode Thermal Labels with C# & VB.NET

ThermalLabel SDK for .NET is a .NET Standard Class Library (DLL) that lets you to create advanced barcode labels and print them to Zebra ZPL/EPL, EPSON ESC/POS & Honeywell-Intermec Fingerprint Thermal Printers by writing just pure .NET code in VB.NET or C# for projects targeting .NET Framework, .NET CORE, Legacy ASP.NET MVC & CORE, Xamarin, Mono & Universal Windows Platform (UWP)

ThermalLabel SDK can be used for designing and printing from simple to complex labels layout supporting Texts, Barcodes, Graphics and Images, RFID Tags, and Shapes like circles, ellipses, rectangles, and lines. It provides an unified object model which will allow you to create one label design and print it to either Zebra, EPSON & Honeywell-Intermec printers getting the same output printing!  General purpose printers (non thermal printers) are also supported by printing in graphics mode as well as Color label design.

 Web API for Docker!

We also offer the ThermalLabel Web API for Docker as a Linux image so it can be used with Any Development Platform and Programming Languages (.NET, Java, PHP, Javascript, Python, Ruby, etc.)

Exclusively Designed for .NET Thermal Printing Scenarios

 .NET Cross Platform Support

ThermalLabel SDK was built as a .NET Standard Library which allows it to be used in any project targeting .NET Framework, .NET CORE, Legacy ASP.NET MVC & CORE, Xamarin, Mono & Universal Windows Platform (UWP) platforms.

 Zebra, EPSON & Honeywell-Intermec Compatible

ThermalLabel SDK provides .NET label design and printing for any Zebra-compatible Thermal Printers supporting ZPL® or ZPL II® (Zebra Programming Language) or EPL (Eltron Programming Language), EPSON printers supporting ESC/POS® as well as Honeywell-Intermec printers supporting Fingerprint® commands.

 Simple Object Model

ThermalLabel SDK provides a flexible programming object model that allows you to create one label design and print it to either ZPL, EPL & Fingerprint printers getting the same output printing! ThermalLabel SDK will let you to create from simple to complex layouts without efforts writing pure .NET code in VB or C#. ThermalLabel SDK generates native ZPL, EPL, ESC/POS & Fingerprint commands. Printing job is fast and you get best performance.

 .NET Data Binding Support

ThermalLabel SDK was designed considering .NET Data Binding scenarios which mean you can bind text and barcode items to .NET data sources. It provides support for most common data types used in data binding scenarios like Arrays, Lists, ADO.NET Access or SQL Server DB, XML DataSet, Custom Objects as well as CSV files!

 Counters - Print Range

Counters allow you to index data items by a selected increment or decrement value, making the data items increase or decrease by a specified value each time a label is printed. Learn how to print 10 barcode labels for values ranging from "ABC01" to "ABC10" leveraging Counters feature!

 Data Masking & Formatting

Data Masking allows you to serialize data items by specifying a Mask string as well as an increment string. It's useful for batch printing scenarios when serialized items are involved. Learn how to create and print a barcode label for a serialized product

fx 100+ Dynamic Expressions

Expressions can include a combination of variables, constants, operators, functions, and references to label Items as well as to data fields in a data binding scenario.
Expressions are set to any Item in the label to dynamically set the Item's content based on the expressions result.
ThermalLabel SDK ships with 100+ built-in well-known functions. It also allows setting and adding your own Custom Expression Functions and Variables/Constants.

   Full Color Label Support

In addition to create monochrome labels for thermal printers, ThermalLabel SDK also supports full color label design and generation and can be printed to any general purpose printers i.e. non-thermal ones in graphics mode.

Text, Pictures, Shapes & RFID

Text items supporting multi-line, content alignment, sizing, Unicode, RTL (Hebrew, Arabic, etc.), Custom and installed Windows TTF files, White Text On Black, rotation, horizontal alignment, counters, and text masking.

Graphic, Image & Picture items supporting image formats like GIF, JPG/JPEG, BMP, and PNG; monochrome conversion features like Threshold and Floyd-Steinberg algorithms and reversing; sources image like files, base64 as well as binary content.

Shape items supporting Tables/Grids, Lines (horizontal, vertical, and diagonals), Rectangles with rounded corners, Circles and Ellipses.

Repeater items supporting fixed count and data bound items repetition.

RFID items supporting ASCII, HEX as well as EPC Data Structures. (NOTE: Only available for ZPL & Fingerprint printers)

First-class Barcode Support Out-of-the-box

ThermalLabel SDK supports most popular Linear (1D), Postal, Component Composite & 2D Barcode Symbologies including Code 39, Code 128, GS1-128, GS1 DataBar (RSS-14), EAN 13 & UPC, Postal (USPS, British Royal Mail, Australia Post, DHL, FedEx), Data Matrix (including GS1 & DMRE versions), QR Code (including GS1 version), PDF 417, Aztec Code, UPS MaxiCode, Chinese Han Xin Code, IFA PPN, all EAN/UPC Composite Barcodes (CC-A, CC-B & CC-C), DotCode and many more barcode standards
You won't need to acquire additional third-party barcode generation software! Neodynamic is an expert in the barcode field and we have incorporated our flagship Barcode Professional algorithms within ThermalLabel SDK

GS1-AIM-ISO/IEC Compliance

Our barcode algorithms were written by following the official specifications of each barcode symbology. Our barcode engine within ThermalLabel SDK provides you with exclusive features like auto-checksum, data validation, Bar Width Adjustment (BWA) for linear & 2D symbols, auto-encoding methods for shortest barcode symbol generation.

XML/JSON-based Label Formats

ThermalLabel SDK handles label designs in a plain & simple XML/JSON-based format. By invoking a simple class method you can get a string representation of the thermal label in XML or JSON formats allowing you to save or store it in any kind of data source be it SQL Server Database, file on disk, memory stream, etc. In the same way, you can restore or open the thermal label definition from a XML or JSON Template by just invoking a simple class method as well.
