Q. Downloaded PDF files won't appear on screen for printing. All I get is a small box with a circle, square, and triangle in it.
A. Are you downloading these PDF files first and then trying to open them or are you opening them within your web browser? If you are downloading them first make sure that Adobe Reader is the program trying to open the files and that they are not associated with another program.
If you are trying to open them from a webpage in your browser you may have a problem with your Adobe Reader plug-in for Internet Explorer. You may want to update or reinstall Adobe Reader to see if that helps. Or you can try downloading the pdf file first and then opening them without using your web browser. You can do this by right clicking the link for the PDF file and then picking Save target as and choosing a location on your computer to save the file. Then double click the downloaded file to open it.
