Duplicate content and robot.txt

Could robot.txt disallow avoid content duplicate?

[henry0]

A “Print page” content duplicate question:

Site: PHP and MySQL using Object Oriented Programming
The print page is dynamically generated

Without debating on print page technique

I would like to be sure that if I disallow the print page in robot.txt
My print page will not be considered as duplicate content

Is the print page needed? Absolutely it is a major factor in this site; I have a program that upon payment delivers a set of pages with answers tailor-made to each user’s special requirements.

<<< edit
While thinking about it I am wondering if there is any content duplicate at all?
Actually I do not think so
since each page will have the same paragraph headers
but a content based upon user's requirements
so possibly I should not worry?
/edit>>>
Thank you

Regards

Correct, there is no real need to worry. In any case, you don't really want visitors coming into the site from the search engines to the print page.

Thank you very much
I can now move forward

Very interesting idea. I have a site that contains affiliate links and adsense. I want to provide the same content without the commercial stuff to a small group of people in a listserv I belong to. No commercial stuff allowed there.

The site is making money, so I don't want to take the ads off. I just want to copy it to a subdomain without the ads and tells my colleagues the url.

If I disallow robots on every page of the copy, can I escape the duplicate content penalty?

[engine]

Yes, because the search engines will be banned from spidering the duplicate.

If they can't spider it, they can't run any dupe page checking.

Thanks, engine. I was thinking that would be the case, but I wanted to hear it it from an expert.
