Since your post is only couple days old, I see they still have not fixed the problem. What is going on with Adobe? This problem exsisted since the release of version X. If you print more than a couple pages, you get garbage. I went back to version 9 till they fix the problem. You will find a post I started that goes on and on about this printing issue.
In total desperation I went back to 9.4.5 today after reader X gave me complete garbage on a ONE-PAGE document in very simple text only!!
I am still concerned that 9 does not have the answer to hostile hacking and nobody has put my mind at rest about that but I simply have to have a version which actually works and I don't trust smaller companies to have the answer if Adobe doesn't (call me naive).
This is really amazing, this problem has been going on since I noticed it in May 2011 and still has not beed fixed. I too went to version 9. All is good. I am still running Adobe acrobat 7 in fear of going to version X. Using adobe reader 9. Well, let's see how long it takes to get version X to print properly.
