We're on Windows XP SP2 on very new PCs with no printer driver changes. The Reader version is now 8.1.2, and a simple, black and white 1 bit PDF file that took a few seconds to print before, now takes minutes to even send to the printer after the upgrade. (The last work station that upgraded this morning is now complaining of the exact same issue.) I've even tried removing my SOPHOS anti-virus to see if that's the issue - no change in Reader's print performance. All other applications print fine. I can't seem to troubleshoot the problem, but I believe it's something Adobe changed in 8.1.2. Any ideas?
