I understand your concern and I'm trying to help solve your Problem please implement the provided instructions I hope are helpful for you.
In your e-Learning tool (e.g., Storyline), add a button element to your slide.
Select the button, and in the trigger settings, choose to "Jump to URL/File."
Enter the direct URL of the PDF file you want users to download.
Test the button in your course to ensure it works as intended.
Now, when users click the button, it will trigger the download of the PDF file directly to their "Downloads" folder, without opening the print window.
Thank you!
