what ???
In actually printing the data -
(in my experience) -
from a PDF file, there's a lot of blank pages, gobbledegook,
extraneous lines criss-crossing, as well as extremely wide margins - all of
which not only wastes paper but makes for a quite messy printed page(s).
So other than those who think they're ecrypting the data why does
anyone use a program which makes such a mess - and as for encrypting the
data; well, I've been able to open any of these PDFs without waiting for
whatever code - after receiving whatever codes, the outcome is never any
better.
