Those three seem to be commercial software (well OK, PaperCut has a free version only for printlogging (no copy) or a 5 users free for copy logging.
Any free versions without limitations? I just need a way to log paper/cartridge usage pr. user.
If not; can it log to SNMP or similar?
If you want Xerox to track it you use XSA.
If you want literally anything else to do it it is no longer a Xerox matter. I listed a bunch of options you can use, it should not be too hard to find more, but if you have specific requirements and expect it to work flawlessly and be free to obtain, it certainly won't be easy to set up. And Xerox won't be able to help you.
