Help Viewing and Printing PDF Files

What do I need to view the PDF files?
Most of the worksheets on our site are in PDF format. To view them, you'll need Adobe Reader. Most computers already have this installed. If your computer doesn't have Adobe Reader, you can download it for free from this link: Adobe Reader
I see a "Preview" graphic over the worksheet.
If you're seeing a "preview" graphic it means you're not logged in. (Sometimes the site automatically logs you out if your computer has been idle.)
First, be sure you entered your name and password. If the preview button still appears, go to your browser's "options" or "settings" menu and clear the cache. The preview button should disappear.
I can't view the files on my computer! I'm just getting a blank page or an error.
If you're logged in and can't download of view files from our website, there are three likely problems:
  • Most likely, there is a problem with your version of Adobe Reader. Please be sure you have the latest version installed.
  • If you're positive you have the most recent version of Adobe Reader, then try to view or download the files with a different browser. (For example, if you're using Firefox, switch to Internet Explorer.)
  • If it's still not working, try shutting down the computer and restarting it from scratch. I know it sounds very basic, but it often works.
  • You might also want to try it from a different computer, especially if you're on a networked system. Sometimes computer network IT administrators block certain sites or certain types of files.
The PDF looks fine on my screen, but when I print the file I see strange characters.
This is a problem for some users who are using the Firefox browser. (Firefox has it's own built-in PDF reader, and it doesn't always allow PDF files to print properly.)
The easiest solution is to use a different browser, such as Internet Explorer, Chrome, or Safari, when viewing PDF files.
In order to print the PDF file properly in Firefox, you'll need to change the default viewer. To do this, follow these steps:
  • Choose the "tools" pull-down menu.
  • Select "options."
  • When the window appears, select the "applications" tab.
  • Scroll down to "Portable Document Format (PDF)."
  • Change "Preview in Firefox" to "Use Adobe Acrobat.
Now, when you view files, they will open up with Adobe Reader, rather than Firefox's built-in PDF viewer. When you print, all characters should appear as you see them on the screen.
When I print a PDF, landscape orientation changes to portrait. Or, a regular worksheet shrinks down to half-size.
These are also known problems with Firefox's built-in PDF viewer.
We recommend using a different browser, however you can change Firefox's default PDF viewer by following these steps:
  • Choose the "tools" pull-down menu.
  • Select "options."
  • When the window appears, select the "applications" tab.
  • Scroll down to "Portable Document Format (PDF)."
  • Change "Preview in Firefox" to "Use Adobe Acrobat.
Now, when you open files, they will use Adobe Reader, rather than Firefox's built-in PDF viewer.
When I print a PDF, dotted lines seem to be missing.
This is a documented bug that exists with Chrome's built-in PDF viewer.
We recommend using a different browser, such as Internet Explorer, Edge, or Mozilla Firefox if possible. The developers of Google's Chrome browser are aware of the issue and are researching a solution.
If you are not able to view and print the desired files using an alternate web browser, you can always save the PDF files to your computer and then open and print them using Adobe:
  • Bring up the desired PDF worksheet with Chrome.
  • Click the "disk" icon located in the lower right corner to save the file.
  • (Or right click on the document and choose "save as".)
  • Check the filename and save the item to your computer/desktop.
  • Locate the file on your computer and open it. It should open with Adobe Reader - which will print the dotted lines correctly as displayed on screen.
