So what they told you was not that RH6 did not support
printed documentation but that it did not support Word 2007.
Yes you have to upgrade if you want to use Word 2007 to print
but you don't have to upgrade to print, you just have to use one of
the older versions that RH was sold to work with. RH6 was never
sold as being compatible with Word 2007.
Also Adobe sold the upgrade from 6 to 7 for about $80 for
many months. You will not find it on the website for that price but
might be worth a call or searching through third party vendor
sites.
Otherwise you need IT to put Word 2003 back on your machine.
You can have a dual install and there is some information about
that on my site.
