can I disable my browser's print function?
You might be able to, but you can't prevent people from taking screenshots of your course and then printing it.
I assume that you are referring to the print button that is located within the actual browser. The only way to "disable" this would be to launch the presentation in a new window by using the method below:1. Open your PowerPoint presentation2. Click on the Articulate menu > Player Templates3. Select the Other tab4. In the Browser Window Settings section, checkmark "Launch Presentation in new window"5. Checkmark "Display window with no browser controls"6. Click the Close button7. Save your Player Template8. Publish the presentation with the newly saved Player Template
Please let me know if this is not what you're looking for.
