SO i did this and it worked:
sudo cp /etc/cups/cupsd.conf /etc/cups/cupsd.conf.original
sudo chmod a-w /etc/cups/cupsd.conf.original
then this:
sudo systemctl restart cups.service
and then i could install and use my printer. I have no idea why printers arent working, or why you have to rename cups.conf files but whateves. it worked…
