Adobe Acrobat X 10.1.14, prints mostly blank pages

I am a registered user of Adobe Acrobat X v. 10.1.14. Am I running Mac OS 10.10.3. I use a Brother HL-5370DW laser printer with the latest print drivers. My pdfs are printing mostly blank pages. If I use PDF Reader.app, my files print correctly. How do I get my very expensive Adobe Acrobat to print all of the pages in my files correctly?
