HTML onbeforeprint Event Attributes

The onbeforeprintattribute is an event handler in HTML that executes a JavaScript function before the print dialog opens. It is commonly used to make temporary adjustments to the webpage content, layout, or styles specifically for printing purposes. This attribute enhances user experience by ensuring the print view is clean and optimized.

Defining HTML onbeforeprint Event Attributes

The onbeforeprintevent fires immediately before the print process starts (i.e., when the user clicks the print button or invokes the print command). Developers often use this event to apply specific changes, such as hiding or modifying content, adding print-friendly elements, or applying custom styles via JavaScript.
