For anyone who has noticed of late that some printouts are appearing mirror imaged you might want to take note of this thread

Seems Adobe reader and HP printer drivers in particular do not see eye to eye and you will find that once it's borked you need to restart whatever adobe program you're using to get it to print properly again.

If ever there was a reason to return to Adobe Reader 7.x this was it..

Naturally Adobe are blaming everyone else and HP say that Adobe always fubar their drivers... gotta love the blame game..
