2013-10-12 PDF is just a format or is it?

Find the article you want on Google Scholar, timely and on point and then  download PDF file and print.  Easy as 1, 2, 3, but by page four any way I do it, it is off center and over the page UNLESS I make it really small.  What’s up with that?  I am going back to the oldest working computer (XP) I have and see if the powers that add all these modular apps have done it again and messed up the formating. Whoa, nelly, slow and accurate before you distribute software.
