gunzip cnijfilter-mx430series-3.70-1-rpm.tar.gz
tar xf cnijfilter-mx430series-3.70-1-rpm.tar
rpm --install <whatever the .rpm file(s) might be in the tarball>

Sometimes the firmware in the printer is different between countries; sometimes it's just that the language supported is country-specific.
Either way be aware that the driver installed from this file might not work correctly (or at all) with your system and/or your printer.
It's good it's an RPM, since you'll have the ability to cleanly uninstall if it causes problems or just doesn't work.
