I am running 10.3 trying to print a simple multi-page doent double sided to our xerox doent center 265. I am using current drivers, the options show up and I can check them ok but when the job comes out its single sided, I try a different B&W copier on the network same thing, if I print from acrobat 5 it works, if I print from Preview it works, but not Acrobal 6. what am I doing wrong?
