Issues getting CUPS up and working for printers first time

So I've been trying to set up CUPS following the Arch Wiki guide and have followed every step to the tee, even going back and rechecking.
When

sudo lpinfo -v

showed up with no result (and the web interface not finding any printers), I checked the error_log and I'm willing to bet it's something to do with the permissions...
I'm not sure why exactly, as I do not recall changing or explicitly setting any permissions, and I used root login with the web interface to reach admin.
I've been searching around for a few hours trying to find solutions without just messing with permissions irresponsibly on the directory, but I have not seen anyone else with any similar problem.
Any advice on what I should do next or where I should look would be very appreciated.

error_log :

Re: Issues getting CUPS up and working for printers first time

So at this point I'd be checking which packages "own" the directory (pacman -Qo /usr/lib/cups/backend/), uninstalling them, and removing the directory, and then reinstalling the packages that you want.

My best guess is that you've installed a driver with bad permissions, and then the cups package, leading to the problems you are seeing?
