   It alters the expected behavior of browser chrome while not actually
securing the content. All one would have to do to circumvent the events
is to create a fork of Firefox or an extension that turns off the
print-related events. Why provide events that tamper with the normal
behavior of a browser function without actually providing added security
for the web developer? The onbeforeprint/onafterprint events only serve
to harass the users, and it doesn't actually enable you to do something
you couldn't do with a reasonable workaround (see my earlier Mapquest
example).
