equivocal

If you layer packages with rpm-ostree, they are not temporary. Although, I would try to keep it to only things in the distros default repos because dependency issues will just cause updates to no longer apply.

On Linux, it is just more important that guides be written for the distro you are using or at least related ones. So, more popular long-standing distros just end up with more guides or better documentation.

Bazzite might not install printer-driver-brlaser by default. If you ran rpm-ostree install printer-driver-brlaser in a terminal what does it say? If you get an “already provided by” error than disregard this but, if it does install it then reboot.

That guide is definitely not going to work on Bazzite.

I’m on Fedora Silverblue and that package is installed by default. My printer (HL-2395DW) was automatically detected and required no configuration.
