The last time I had to use RH to create printable output, there was a substantial amount of clean-up work involved each time between creating the Word version with all the print-friendly stuff like continuation statements on pages, etc., and then output to PDF and all the security stuff. For a single user guide, I would spend 3 to 5 full days just getting it into PDF from RH. Time is money. You could estimate the amount of time, factor that by your wage (plus the standard fudge factor for dealing with program bugs and crashes), and then factor that by the number of releases per document quarterly. That should be staggering enough to make your case clear to the QA and management mindset.
