$ tail -n +143 z600cups-1.0-1.gz.sh > install.tar.gz # the sh script is broken for newer systems. use `tail` to extract the binary portion of the script.
$ tar -xvzf install.tar.gz # extract the contents produced by tail
$ alien -t z600cups-1.0-1.i386.rpm # convert unusable rpm packages to tgz.

$ sudo tar xvzf z600llpddk-2.0.tgz -C / # extract the tgz's to / putting the files in their right place
