Quite a nice way is to have a SEARCH_RESULTS table, so you might do a search for people in New York, Smith, it would populate the search results table with a unique search id and all the primary keys. Then display the list and allow the user to pick the people it wants to print or print All for example, then pass the search_id and the type (IE All) and then include the search results table in your select statment(s).

Hope this has given you some ideas.
