Pressing the "search" button on that notification hard locked my laptop. I really need to move off of Arch Linux.
Apparently Brother actually packages linux drivers for this label printer but they only provide rpm and deb packages, and my dumbass is running Arch.
A kind soul packaged the drivers in the AUR. Let's see if they actually work.

I think my next step is to pull out one of my old RasPis and throw this baby on the network. That's a task for another day though.
@murph Now I can never unsee it.
@jeffers00n You're welcome!
