hello,

Please, can you show how to use/implement the readOnInterval method ?

Thanks!

Hi,
I tried your code but got this error
An error occured while attempting to connect to your Zebra Printer. You may not have Zebra Browser Print installed, or it may not be running. Install Zebra Browser Print, or start the Zebra Browser Print Service, and try again.
I am using Zebra TLP 2844, OS Linux.

I tried with Zebra GC420t, it did not work. Please help me to get it done.

Hello. I would like to know how I can use BrowserPrint.js from my Reactjs application? I have not been able to integrate that library into my project. Do you have an example?

Hi, I have issues with cors-origin when im trying to send the http request from another ip in the network , is there any config should be passed in the request ?how to fix this problem, plz help.
