OfficeJet Pro 8620 icc Profiles

I have completely failed in my search for ICC profiles for the HP OfficeJet Pro. HP tier 1 tech seem to have little idea what an ICC profile is, let alone what it might be used for. Has anyone discovered profiles for this Printer? Any source HP or otherwise would be better than no profile. I would prefer not to have to go to the expense of acquiring the equipment to create specific profiles myself.
