The good news is that there were updates to the HP printer drivers today which seem to have fixed this issue. My printouts are as they should be now, instead of inverse. My only disappointment is that I reported this issue back on May 14, so I haven't really been able to print from my machine for over 2 months. I've never had an issue before that went this long without at least a little input from one of the devs. Oh well, I'm happy to be able to print. I'm a happy camper.
