Can CSS and JavaScript Customize Print Settings in Web Browsers?

Disabling Default Browser Print Options on HTML Pages

Can you customize print settings within web browsers using CSS or JavaScript? Disabling or modifying the default print margins, headers, and footers can enhance page presentation and reduce reliance on PDF documents.

CSS and @page Directive

The CSS @page directive enables advanced page formatting. It allows you to specify printer page margins, which are distinct from CSS margins for HTML elements.

@page {
    size: auto;
    margin: 0mm;
}

By setting the printer margin to 0mm, you effectively disable the header and footer. However, this method has limitations:

Browser Compatibility

Support for @page directives varies across browsers. Safari does not support setting printer page margins.

Implementation in Different Browsers

• Internet Explorer: Margins are set to 0mm by default, but users can override them in the preview.
• Firefox: Margins are positioned correctly, but both browser headers/footers and page content are displayed, creating a visual mismatch.
• Opera: Page content hides the header when using a non-transparent background, but page margins are not set properly.
• Chrome: Browser header and footer are hidden if the @page margin conflicts with the content position. This provides the optimal behavior.

Conclusion

The @page directive in CSS allows you to disable printer margins, but its effectiveness зависит on browser compatibility. Chrome currently has the best implementation for hiding headers and footers while maintaining print formatting.
