This looks like a very modern gadget.
The ones i know from research, get controller by a computer over USB. You put in an image and press Start so the laser does its thing.
I think bluetooth/wifi just makes these things crazy expensive.
This is the one my brother bought and it works quite nice: https://de.acmerlaser.com/products/acmer-p1-10w-lasergravurmaschine
