We have a Brother QL-820NWB label printer at the office desk in the lab.
It is currently connected to a Raspberry Pi Zero W.
Just go to http://192.168.1.242:8013. You will be presented a web interface, with which you can design/write your label. Afterwards just click on print and it will work.
In future, our stock system Grocy will be connected to it, so you can print label with barcodes for our stock directly.
We have the Nerd fonts installed. So all the fonts with Nerd in the name have icons patched in.
