Description

What type of issue is this?

Browser bug (a bug with a feature that may impact site compatibility)

What information was incorrect, unhelpful, or incomplete?

Safari does not handle print page margins correctly, for example

@media print {
  @page {
    margin: 2in;
  }
}
What browsers does this problem apply to, if applicable?

Safari

What did you expect to see?

The page for @page does not indicate that Safari is missing this feature.

Did you test this? If so, how?

Render this page, and print in both Chrome and Safari. On the printed page, the red box is centered in Chrome (correct), but is not centered in Safari (incorrect). I am using Safari version 17.0 (19616.1.27.211.1).

<!DOCTYPE html>
<style>
  @media print {
    @page {
      size: letter;
      margin: 2in;
    }
  }

  html {
    print-color-adjust: exact;
    -webkit-print-color-adjust: exact;
  }

  #main {
    background-color: red;
    height: 9in;
    width: 6.5in;
  }
</style>
<div id="main"></div>

Start with the MDN @page page and the compatibility-data query css.at-rules.page.size. Reproduce the supplied print example in Chrome and Safari, then inspect the corresponding Safari compatibility entry. Done means the data accurately reflects the verified Safari behavior and passes the repository's validation checks.
