This following URL are the places from I tried code https://www.quackit.com/css/at-rules/css_bottom-center_at-rule.cfm https://www.w3.org/TR/css-page-3/#cascading-and-page-context
But When I print it apply margin from @page rule, but does not update content in header and footer from other define rules.
I attached following picture it is showing what rules are using for change specific area of code

But When I print other @rules not work except @page( set margin correct)

I want to update highlighted area in printed page using below css @rule
Based on the date and URL in the page margins in the screenshot, it looks like you’re using the “Print” functionality of a desktop web browser. Unfortunately none of them support CSS page-margin boxes (such as @top-center) at the moment.

If you’re making a website and want to control how it’s gonna be printed by other people’s web browsers, I’m afraid you’re out of luck.
