First, make sure that you limit your database searches to full text (find instructions here), so that all articles in your search results are available to read, download or print.
Then, when you see an article that is a good fit for your research, click its "full text" link.
Full text links may be PDF or HTML. If an article has both, then choose PDF (it will retain original page numbers and graphics). But, if an HTML copy is the only option no worries. It will still give you the same content.

In an HTML article, look for "Save" or "Print" options and click them.
