Qt5 - print webview html doesn't fit the paper

I am trying to print html. I set the html to a webview, and then I'm trying to print the webview's content. When I open the html contents in browser - it looks just fine. But when it prints - a part of content (it's right side) is cuted of (it just seems like it's not fitting the paper area). I am just wondering - is it possible to make the printed content to be auto-fitted, regardless the actual paper size (printer's to which I'm printing may differ)?

Thanks in advance
