You are welcome to download and save/print most all documents in CAC public courses. (Video and audio files, including chants, cannot be downloaded, however.)
On each page with a document, the document will display on the page. There is also a "download" icon.
When you click the download icon, that file will be downloaded to your device. The location of this file will depend on what type of device you are using.
Once the file is downloaded to your device, you can save it in the location of your choice, or you can open and print it using whatever printing options you have available.
