Viewing the PDF documents requires the Adobe Reader or another program that will read PDF files. If you do not have it, you can get it by clicking on the Adobe logo.
When printing the documents, some pages may print too close to the edge. To avoid this, in the Print window, about half-way down on the left, under "Page Handling" is a selection list for "Page Scaling" - select the option for "Reduce to Printer Margins" or "Shrink to Printable Area."
