Automatically download a slide/certificate

One of the challenges I've been having recently is where users will complete a SCORM-based module, but it doesn't report back into the LMS.  This could be for a variety of reasons but I'm looking to create a workaround that doesn't involve getting learners to retake the module - so I'm looking into a solution which involves downloading a slide automatically which I can populate with variables.

I'm aware that you can download a slide by having a "Print Results" button, but this will open the slide I want in a print view; then I have to select "Save as PDF" and then click "Save"; then find the folder where I want to save it... it's a bit of a hassle.

I want to make this as easy as possible for the user to download, almost like it's happening in the background, and not require them to go through all the above actions.

I'm not versed in JavaScript or HTML5, but if that's the only way to do this then open to suggestions - if it's possible at all!  I've been looking through the discussion threads but not turning up anything which really helps me with the main goal of what I want to achieve, which is creating a button which automatically downloads the slide.
