Okular - how to print A3 doc on two A4 pages?

Hi Community!

Is there a hint to print a A3 document on two A4 sized pages with Okular?

If I set in the option “print in original size”, I get only the first side of the document.
It the option is set to “shrink to printable area” or “adjust to the whole side”, I get the whole document but on only one page (obviously) - that is not practical because the type size.

Thanks a lot in advance for suggestions!
