suppose you're invited for an interview
how about and you want to prepare
yourself
you received this nice password
protected PDF file which is assumed to
help you
unfortunately as you can see i'm not
allowed to print this file i don't know
why they blocked this option if we are
not used to read from the computer
screen it would be better to bring this
file this whole situation reminds me of
blocking right mouse click and browsers
to not all people to see the source of
the document which is equally stupid in
my opinion anyway if you want to print
this document will have to convert the
file with no protection we will achieve
this result using PDF Crocker will just
use standard ghostscript render
available you can download to go strip
transfer from go straight comm unit one
of the versions available on this
website in my particular case I don't
know that this 64-bit version after the
installation of your script will have to
run command line and just run a simple
comment to print render this PDF
document to another one without any
protection so let's paste the command i
prepared before and now as you can see
we're on your street stripped for
Windows command line tool installing
profiles we use our as PDF password
option and the ghost device which is
speedy of right and output file name you
can choose whatever you like and the
source file name and when I percent of
the conversion begins no script renders
each page separately into the another
document so let's open the generator
document as you can see the generated
file as option to print and it's no
longer protected
