I am creating a MERN app. I am wondering if I can connect my computer to a printer from an ip address and that printer is far away.
like we connect with ssh or ip address to connect our web server. in which language it is possible just thinking...
With your app, I think the easiest way is to let the Nodejs handled the auto receipt printing service.
I have created a simple diagram to show you how the system would work.

I want to make a chat application (something like on how is on Whatsapp Web). I want my application to be on laravel.
I just finished the design and the login system.
My question is about functionality.
Is it enough Laravel and Javascript or do I need something else additional?
I don't need to make a large project, its just for me to start learning the basics things and how they work.
Laravel for backend, JS for frontend
You also need Pusher (if not big project) for (easy) real-time application and pusher-js for subscribe websocket
You need to add a websocket part , in order to make the app real Time.

I have been trying to add a voice chat for multiple users (like a Discord voice channel), for my Discord clone project.
After too long, I got it to haphazardly work with 2 people max using PeerJS. I'd like to extend this to more than 3 people. I have done research and I have found not much help for this.
I am using socket.io, an express.js API - https://github.com/theADAMJR/discord-voice-chat.
How would you add multiple user voice chat in a NodeJS web application?

Currently we have this certificates for our IOT project
private.pem.key
public.pem.key
rootca.pem
certificate.pen.crt
I have tried using this link, but can't link the above certificates.
https://eclipse.org/paho/clients/js/
Any libraries recommendation would be helpful as i am not expect in this field.
Thank you
You can not do certificate based client authentication from the Paho Javascript client within the browser.
To use MQTT over Websockets with AWS you have to use the signature based Authentication as described in the AWS IoT documentation here:

I am going to develop a admin tasking system using PHP, MySQL, JavaScript . How the notification system works and how they save real time data. is there there any example of notification system .
Pusher (https://pusher.com/) is great when it comes to real time, and it's not expensive.
I've been using it on a project of mine for chat, and it worked flawlessly.
They also have tutorials, and particularly, they have one on how to create real time notifications. Here's the link: https://pusher.com/tutorials/realtime-notifications
I think this is perfect for you. It's simple, and while you're building your system, it's free.
