In the realm of web development, it is often necessary to control the appearance and layout of documents printed from a web page. However, by default, browser print options including headers, footers, and margins may not align with desired design specifications. This article explores ways to modify these settings using CSS and JavaScript, providing browser-specific solutions and addressing potential limitations.
Using CSS
The CSS standard provides the @page directive, allowing developers to specify printer settings that apply specifically to paged media. By defining page margins within this directive, it becomes possible to alter the page layout for printing. However, it is important to note that browser support for this feature varies.
For example, the following CSS code can be used to set printer margins and specify background color:
@page { margin: 0mm; background-color: #FFFFFF; } html { background-color: #FFFFFF; margin: 0px; } body { border: solid 1px blue ; margin: 10mm 15mm 10mm 15mm; }
Addressing Browser Incompatibilities
As mentioned earlier, the behavior of @page directive can differ across browsers. Safari does not support setting printer page margins, while other major browsers like Google Chrome, Firefox, and Opera show varying levels of support.
Disabling Page Headers and Footers
In some cases, it is desirable to remove browser-generated headers and footers. This can be achieved by setting page margins to 0mm in the @page directive. However, it is important to note a quirk in this approach.
When page margins are set to 0mm, the margin specified for the body element will not be used for page breaks. This means that if the printed content spans multiple pages, these margins will not be applied.
Conclusion
While browser inconsistencies can pose challenges, developers can leverage the @page directive in CSS to customize browser print settings, including margins, headers, and footers. Understanding browser-specific limitations and implementing workarounds is crucial to ensure a consistent print experience for users across different platforms.

Use max-width:100% and height:auto to allow the image to adapt to the container width while maintaining the proportion; 2. Use HTML's srcset and sizes attributes to intelligently load the image sources adapted to different screens; 3. Use object-fit and object-position to control image cropping and focus display.
