We're developing software to connect with Zebra printers on React web application. But we couldn't be successful at this and the zebra sources are outdated!

We couldn't use their SDK because it was outdated and when I imported that webpack gave us so many errors that couldn't compile that code. I'm using this SKD wrapper now: https://www.npmjs.com/package/zebra-browser-print-wrapper

I'm getting network error when I'm trying to print using zebra printer.

instrument.ts:159 GET http://localhost:9100/available net::ERR_BLOCKED_BY_CLIENT
Error: TypeError: Failed to fetch

I'm using the sample code in the NPM js package that I've shared.

Zebra software and devices are configurated and working but it doesn't work when I'm trying to connect to it using web application.

Does anyone know how to work with it?
