I'm extremely interested in knowing more about this, since it's
relevant to some of the things going on here . . . looking around
the web, I have gotten a lot of very confused information, so any
one with experience like this, I'm interested in hearing about it.
But, one question:

Are all of you speaking of printing out the PDF and then
scanning it? . . . if that's not what you mean, please explain. If
that is what you mean, can it be done without the print out/scan
steps?
