Build Thermal Printer integration to web app (VueJS + Quasar)

So in short I have a system similar to foodpanda, Uber eats and so on. The restaurant have a tablet or similar in the place.

I need the possibility for a Thermal Printer to connect to it. It's a Web App (VueJS), so it might not have access to etc. Bluetooth. It's a PWA and therefor web based.

So there are some possibilities:
1. Look at tastyigniter.com and their plug-ins for what has already been created or used (https://tastyigniter.com/marketplace/item/thoughtco-printer)
2. Foodooma also has a thermal printer module: (https://codecanyon.net/item/thermal-printer-module-for-foodomaa/30280239)
3. Check printnode.com and how to utilize that
4. Check PaperCut Mobility Print
5. Setup a print server with a Raspberry PI as a print control box/ print server.

I need the best and easiest solution.

Thanks
