feature request from user - pdf download to print

[storeofvalu]

A kind request (if possible): It would be great to have the article
downloadable as a PDF as it is not properly printable at the moment.

This is just coming from someone who prefers to read on paper instead
of the screen.

Reader view already works (Safari, Chrome) - is there a way to easily implement a solution to

1. force reader view with a button (client side)
2. auto generate pdfs with SBI branding (for download)
