FAQS

What if my file isn’t printing correctly?

ZIP FILES:
If you're experiencing issues with printing, first check the file type. If it’s a ZIP file, you’ll need to unzip or extract the contents before printing.

How to Open a ZIP File:

On a Windows Computer
:

  • Right-click on the ZIP file.
  • Select "Extract All..." from the dropdown menu.
  • Choose the location where you’d like the extracted files to be saved.
  • Click "Extract" to uncompress the files.

On a Mac:

  • Double-click the ZIP file. 
  • The contents will be automatically unzipped into the same folder as the ZIP file.

Once unzipped, you’ll be able to access all the files contained within the ZIP archive.

PDF FILES:

For PDF files, especially those with many graphics, the file may display correctly on your screen but not print as expected. To resolve this, make sure you're using the latest version of Adobe Acrobat Reader to open and print your PDF.

Once Adobe Acrobat Reader is installed:

  1. Open the PDF in Adobe Acrobat Reader
  2. Click "Print.
  3. In the “Page Sizing & Handling” section, select “Shrink oversized pages” if needed
  4. Click “Advanced.
  5. Check the “Print As Image” box
  6. Proceed to print your document.


What if I can't download a file?
If you're having trouble downloading a file, it's usually a temporary issue caused by an unstable network or a browser connection problem. If you see a network error message, try refreshing your browser and attempt the download again after a few minutes. In most cases, this will resolve the issue.

If you're using a school computer, keep in mind that some schools have restrictions on downloading files. If this applies to you, try downloading the file at home and then transfer it via a USB drive or email it to yourself.

You can also try right-clicking (on a PC) or control-clicking (on a Mac) the download link and selecting "Save target as" or "Save link as" to download the file directly to your desktop.Need help or have further questions? Don’t hesitate to contact us!
