I have a ZPL code to print a Datamatrix, the result on ZPL visualizer seems accurate (see image below) but I'm unable to scan it with my scanner app, and a random QR reader says it's an invalid QR.

I Use .html for visualizing

• Why would you expect a "random QR reader" to read a DataMatrix barcode? Those are two entirely unrelated things. – jasonharper Commented Mar 20 at 13:58
• Please post a pic of the generated barcode from the zebra printer. Why do you think a qr code app will read a datamatrix barcode? Does the app say it reads datamatrix? – Mark Warren Commented Mar 20 at 13:59
• It's an app I always use to scan datamatrix, but maybe I shouldn't depend on it. The issue is, even my app that reads data matrices is not capturing anything, here's an example: julebcom-my.sharepoint/:v:/g/personal/raghad_juleb_com/… – Raghad Alafeef Commented Mar 20 at 14:25

Make sure you Prefix your data with ^FD command.

Labelary shows errors that you have in your ZPL, make sure to review those.

Also, either read the Labelary details of the ^BX command, or read the ZPL documentation so you understand the commands you are passing it. The commands you are using will not allow for a readable barcode.

This produces something scannable:

^FO40,40^BXN,4,200,32,32,,~,1^FD_10100301320005257_1102416099_117260520_12124160992605000008^FS

I found a solution, I checked the example in the docs here (page 146) and removed unnecessary parameters from my command, and added ^FD following the comments here, and it works now :D

Before:

^BXN,7,200,20,20,,_

After:

^BXN,6,200 ^FD

It works without the hash as well, but I added is as an extra separator, will keep it if the printed QR is still accurate.
