Print slide

Hey!

I got a small problem.

I've made a course, with custom quiz scoring since the one in CP did not work to my needs.

I need a certificate at the end, but the one in CP does not work with custom variables.

So, I've created a slide for this.

This is where my problem starts.

I need to print this.

The print button in the playback control does not work, so I created my own with JS "window.print();"

This will print the slide, but the slide is to big to fit. It is to wide for normal portrait ofc, but its to wide and to long for landscape.

Is there a way to fix this? Or, is it possible to have a script just print an object or a group?

Thanks in advance!
