Summary

The property onbeforeprint sets and returns the onbeforeprint event handler code for the current window.

Syntax

window.onbeforeprint = event handling code

Notes

Some browsers (including Firefox 6 and later and Internet Explorer) send beforeprint and afterprint events to let content determine when printing may have occurred. You can use this to adjust the user interface presented during printing (such as by displaying or hiding user interface elements during the print process).

The event beforeprint is raised before the print job dialog appears.
