The View document as PDF page does not immediately display the document. Instead you must select the default page/page range or specify a page or range of pages you wish to be displayed as a PDF. The entire document, whether one page or multiple pages, is the default number of pages in the Page range box (See Image 1 below).
Once you specify the page/page range, click the View document as PDF button. A new tab or window will open containing the PDF document. The tools available at the top/bottom center or bottom right corner of the page depends exclusively upon which version of the Abobe Acrobat Reader is loaded on the computer being used (see Image 2 below).
