When using the Browser Print SDK, please be sure that the JavaScript code is hosted on a webserver and accessed through HTTP or HTTPS via a browser. If the JavaScript is opened in a browser from a local folder, we may see various issues. When you open the webpage of the JavaScript in a browser the very first time, please click on the Yes button to grant the access to the printers from the domain.

Make sure to use the supported browser, such as Chrome, for the Browser Print. You can also take a look at the logs for the errors for debugging. Logfile location: C:\Users\username\AppData\Local\Zebra\BrowserPrint\log.txt (Windows) or ~/.Zebra/BrowserPrint/log.txt (MacBook)
