Features at a Glance

 Zebra, EPSON & Honeywell-Intermec Compatible

ThermalLabel Web API converts label designs or templates to Zebra-compatible Thermal Printers supporting ZPL® or ZPL II® (Zebra Programming Language) or EPL (Eltron Programming Language), EPSON printers supporting ESC/POS®, HP printers supporting PCL® as well as Honeywell-Intermec printers supporting Fingerprint® commands.

   Full Color Label

In addition to create monochrome labels for thermal printers, ThermalLabel Web API also supports full color label design and generation and can be converted to JPEG/JPG, PNG, PCX, SVG, HTML, and PDF formats.

fx 100+ Expressions/Formulas

Expressions/Formulas can include a combination of variables, constants, operators, functions, and references to label Items as well as to data fields in a data merging/binding scenario.
Expressions are set to any Item in the label to dynamically set the Item's content based on the expressions result.
ThermalLabel Web API ships with 100+ built-in well-known functions.


 Data Merging/Binding Support

ThermalLabel Web API was designed considering Data Merging/Binding scenarios which mean you can merge/bind text and barcode items to XML & JSON Array data sources.

 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. This feature allows scenarios like generating 10 barcode labels for values ranging from "ABC01" to "ABC10".

 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. This feature allows scenarios like generating a barcode label for a serialized product 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).

Text, Pictures, Shapes & RFID

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

Graphic, Image & Picture items supporting image formats like JPG/JPEG, 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 Web API 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

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 Templates

ThermalLabel Web API handles label designs in a plain & simple XML/JSON-based format. These string representation of the thermal label in XML or JSON formats allow you to save or store them in any kind of data source be it Database, file on disk, memory stream, etc. The XML/JSON Label Template can be generated in you preferred programming language or visually through the ThermalLabel Web Editor Add-on.


ThermalLabel Web Editor Add-on

How to configure Custom TTF Fonts

Most labels that are designed might contain some texts, and these texts need to be rendered by using a given set of fonts. To make these fonts available for the ThermalLabel Web API for Docker to preview, render and convert the labels to the target format, then a special configuration must be performed.

NOTE: Fonts that are added to the ThermalLabel Web API for Docker remain the exclusive property of their specific owners and require a license from their owners.

The following steps show how to configure the ThermalLabel Web API for Docker to add support for Arial Unicode TTF font for rendering texts in different languages.

Custom Fonts Configuration Steps

  • Be sure you download the Arial Unicode font (in some Windows systems, that font is located at c:\Windows\Fonts\ARIALUNI.TTF). Remember that any added font remain the exclusive property of their specific owners and require a license from their owners.
  • Once you have the ARIALUNI.TTF font file, copy it to the Linux box where the ThermalLabel Web API instance will be running on.
  • In the home dir of your Linux box, create the following directoy: MyThermalLabelSettings
  • Copy the ARIALUNI.TTF to the MyThermalLabelSettings directory
  • Create a plain text file and name it to fonts.json and then write or copy/paste the following content: 

    
[
  {
    "name": "Arial Unicode",
    "fileName": "ARIALUNI.TTF"
  }                                
]

    This is a JSON Array for each font you want to upload to the virtual printer storage. Each JSON object representing a given custom font must be specified with the name of the font (which is just for your identification only) and the fileName which points to the physical font file.

  • Finally, to make the custom fonts available in the ThermalLabel Web API instance, we have to mount a volume to the instance in this way:

    AMD
    docker run -it -v ~/MyThermalLabelSettings:/app/Config --rm -p 8080:80 neodynamic/thermallabelwebapi:4.0.12
    ARM
    docker run -it -v ~/MyThermalLabelSettings:/app/Config --rm -p 8080:80 neodynamic/thermallabelwebapi:4.0.12-arm64

 Evaluation Mode

The Trial Version of ThermalLabel Web API for Docker is fully functional and has no expiry date. However, while in TRIAL mode, the output rendering has the following limitations:


  • SVG barcode image formats require a license key, a blank image will be generated in TRIAL mode.
  • A TRIAL stamp will be rendered at the top of the rendering output.

 Want to try ThermalLabel Web API for Docker without TRIAL watermark?

We offer you a 30-day Evaluation License Key which will allow you to test the ThermalLabel Web API for Docker in fully-functional mode for 30 days! When the 30-day Evaluation License Key expires, the ThermalLabel Web API for Docker behavior backs to Trial mode. Request your 30-day Evaluation License Key now...
