When printing a slide in chrome I have to set the "Scale" parameter to around 80%

I would like to print a Storyline Slide in A4 format in Chrome. The project has the dimensions 595 px x 842 px and I'm working with the "window.print();" Javascript. Basically everything works fine, except that it cuts the edges in Google Chrome, so I have to scale the whole thing to about 80% in the printing settings. Is there a way that Chrome does this automatically?

Thank you for the answer and best regards,
Simon
