Lana_Prolific,
Perhaps you can provide us with some more information. What is the defined page size of the pages you are trying to print? Also, what is the page size you have selected on the Xerox 700 printer? Does the same problem occur when you attempt to print the same pages to other printer models? You also might want to consider checking whether Xerox offers an updated driver for this printer for MacOS 10.10.
More info and we might be able to assist you further. FWIW, this is not an issue that we have previously heard about either through these forums of the Technical Support organization. At this point I would not make any assumptions as to whether MacOS 10.10 or Acrobat 11.0.10 is the culprit.
