Freihut [1] filed a deletion request for samsung-ml1660series [2]: It seems that this package is broken: Tested this on 2 machines and couldn't get the printer to work.
By using https://aur.archlinux.org/packages/samsung-unified-driver I was able to print stuff just fine, so I assume it wasn't a printer nor configuration fault. [1] https://aur.archlinux.org/account/Freihut/ [2] https://aur.archlinux.org/pkgbase/samsung-ml1660series/
