Got a basic brother laser printer from walmart for $100 a few years ago. The toner reset sequence actually works! only problem is the wifi died 6 months ago but it still prints great!
no need to reinstall, a running system is always fixable, if you need networking try wired ethernet with a usb dongle or a usb wifi adapter or bluetooth/usb tethering to a phone
maybe start by running pacman -Syu again, in case it magically fixes itself.
Check dmesg for wifi related errors
figure out what wifi device you have and what kernel drivers support it
check that the driver module is available, try loading it manually with modprobe
reinstall relevant kernel modules. Hopefully this will fix whatever is wrong.
