Today Acrobat X refuses to print in duplex. It has also failed to recognise my default print HP LaserJet P2105 and grabbed the last one I used in Entourage. Even if I set the HP Printer in the Print menu and make certain it is my LaserJet, Acrobat won't print Duplex. It also refuses to print anything unless I set shrink to fit page.
This is unusual behaviour as Acrobat 9 Prof worked perfectly.
Any ideas/work arounds?
I am running OS 10.6.6. I have also cleared all Adobe caches and restarted. Nothing helps.
