The API service will convert any HTML document into a ZPL. It executes style sheets, loads images, and even executes JavaScript - just like you’re used to from your Desktop browser. The HTML to ZPL API is an great way to embed arbitrary media inside a ZPL label without resorting to writing ZPL yourself.

API Parameters

The HTML to ZPL API accepts 3 parameters:

• height a positive number denoting the height of the label, units are inches.
• width a positive number denoting the width of the label, units are inches.
• html the html content you want to render into a label.
  Note that HTML or body tags are not required. Think of it as just providing the contents to the body tag, anything that is valid in the body tag of an HTML document is valid here. You can also embed JavaScript inside the html parameter your pass the API.

Upon a successful API call, raw ZPL is returned. You can save it to a file and print it or send it to a networked Zebra label printer.

Example using the Command Line

A brief example that can be executed on the CLI is provided below. You will need to have curl installed on your machine.

To run this example please first subscribe to the API using the free plan. RapidAPI will provide you with an API key. Replace the API_KEY in the example with your key.

This command will generate the ZPL code for a 4" x 2" label with some sample text:

curl --request POST \
    --url https://html-to-zpl.p.rapidapi.com/html2zpl \
    --header 'content-type: application/x-www-form-urlencoded' \
    --header 'x-rapidapi-host: html-to-zpl.p.rapidapi.com' \
    --header 'x-rapidapi-key: API_KEY' \
    --data width=4 \
    --data height=2 \
    --data 'html=<h1 font-size:40pt;margin-top:0.5in;>Hello World!<h1>  <p style="margin-top:1.2in; font-size:25pt;">ZPL label generated by <u>htmltozpl.com</u></p>'

After a few seconds, the API will send back the encoded ZPL data:

To see a preview of the ZPL you can use the viewer at http://labelary.com/viewer.html . Be sure to specify the correct size for the label.

This ZPL code can be sent directly to the Zebra printer for printing. If the printer is connected via network, you can send the string over a TCP socket (port 9100). Please contact us if you require assistance or code samples.
