You'd have to define what you meant by "came across". My guess is
that either you or your software got temporarily confused.
The answer to your question, if you really mean to ask the question
"Can I post an FAQ to Usenet such that the vast majority of people
cannot print/save/cut-and-paste it?" is no, there is no established
way of doing so. If you've sent the bits out, then in theory you
can't really prevent me from doing whatever I feel like with the bits
using *MY* news reader software.[*]
A rather pertinent question for this mailing list is why you feel the
need to apply such "protection" to your posting.
-- Yours in Leadership, Friendship, and Service, Ping Huang (INTERNET: pshuang@mit.edu), probably speaking for himself[*] There are some situations which you could almost consider an exception to the above statement that "you can't prevent me from doing whatever I feel like with the bits". For example, I remember reading a review for software which allows you to distribute richly formatted documents --- a well known example would be Adobe's Acrobat, but there are a number of other companies with similar products. Some of these products tout as a feature that you can create essentially read-only documents which the reader cannot easily copy text or graphics from the documents (most of them didn't tout as a feature preventing the reader from printing your document as a whole). However, unless you wanted to limit the audience to those people who have such software already, or unless you wanted to distribute document viewer software along with your FAQ document (but, not all viewers are freely distributable, and you would have to provide viewers for multiple platforms, and not all platforms are supported...), this doesn't help you. And I would bet such software is really only relying on security by obscurity anyway; i.e., if I wanted to strongly enough, I could reverse-engineer the file formats without too much trouble and extract the text and graphics. Or, I could use software to capture the image from the document viewer's window in a GUI environment and then OCR it, etc. However, you would have succeeded in preventing most normal :) people from doing anything with your FAQ other than read it.
