This may seem like a no-brainer, but technology has not invalidated the need for printed copies of important documents. In some interviews, you may meet several people at the company at different times, so bring at least five copies and one for yourself.
In many professions, you may also need examples of your past work in a portfolio. This should be presented in an order that is most recent and most relevant to the potential position. Print at least one full-color bound copy for your interviewers as well as a USB with your resume and PDF of your portfolio to leave with your interviewer so they can review at their leisure.
