Let's take a step back:
What software are you running (Adobe Acrobat or the free Adobe Reader)? Which version, and on what operating system?
Is this with PDF files that are stored on your computer, or with PDF files that you display in the browser? If it's in the browser, then what browser are you using?
I don't know what the "pdf viewer/printer for office docs" is - what exactly are you using?
