This event is usually used in conjunction with the onbeforeprint event. Whereas the onbeforeprint event gives the Web author an opportunity to make changes to the document just before it prints, the onafterprint event provides a means to undo those changes, reverting the document back to its pre-print state.
Although event handlers in the document object model do not receive parameters directly, the handler can query the event object for data.

The following example demonstrates how the onafterprint event can be used to bring the document back to its pre-print state. In this case, since the onbeforeprint event handler made all currently hidden sections of the page visible for printing purposes, the onafterprint event is used to set those sections back to hidden.
Sample Code
function window.onbeforeprint() {
var coll = document.all.tags("DIV");
if (coll!=null) {
// check for class = "collapsed" and set to "expanded" for printing
for (i=0; i<coll.length; i++)
if (coll[i].className == "collapsed") {
coll[i].className = "expanded";
// flag changed class
coll[i].bExpandedForPrinting = true;
}
else if (coll[i].className == "expanded")
coll[i].bExpandedForPrinting = false;
}
}
function window.onafterprint() {
var coll = document.all.tags("DIV");
if (coll!=null) {
/* check for class = "expanded" and flagged for printing
then reset to "collapsed" */
for (i=0; i < coll.length; i++)
if ((coll[i].className == "expanded") &&
(coll[i].bExpandedForPrinting)){
coll[i].className = "collapsed";
coll[i].bExpandedForPrinting = false;
}
}
}
