How to print on a label printer from a browser?

Question

Printers

There is a task to print labels with a number and a barcode from the browser.
Because of this, the question arose, is it possible to print all this from the browser somehow?
If not, then we can write a program that will receive tasks from the site and print, but the question itself is interesting to me: how does all this happen from a programming point of view.
Maybe someone had experience with such printers in their software?

Answer 1

The "label printer" (AKA thermal diffusion/thermal transfer printer) is a perfectly normal printer from the point of view of the system. Just print on it (setting the correct paper size) and that's it.
It's another matter if you don't want to immediately generate a barcode on the page - here you have to shamanize the layer.
