How to print in landscape view in Firefox?

Question

css

Hello!
Faced a problem with printing in the browser in landscape mode in Mozilla Firefox 51.0.1 (32-bit).
No problems were noticed in Chrome, IE is not interesting.
Source: css, js
JS -> jQuery.print, version 1.4.0

CSS Google re-dug, no solution works... It's been tried, it flips, but the content flies somewhere outside the document.
@page { size: landscape; }

-moz-transform: rotate(-90deg)

Try adding

body { 
        writing-mode: tb-rl;
}
