That doesn't work in some cases:

* The impression left by a pen or pencil can still be detected.

* There may be ways see some kind of chemical difference between the
printer's ink on the page and the marker.  Or perhaps various kinds of
tricks of science.

Burning is a bit improper these days.. perhaps a shredder and some
sort of grinder would do it..  Two-stage shredding.
