Copiers, fax machines... definitely.  Printers quite probably.  As we move more and more electronic, with no paper being created or received or sent, anything that deals with hard copies will go away.  More and more will be electronic, meaning our "pc's" will be in our hands (like our smart phones, only smarter!), in our vehicles, etc. so we can do our work, view necessary items, whatever, all in electronic format.  (Think the "In Death" series of books by J D Robb (aka Nora Roberts) where she's in the future and there's no paper money, no paper anything.)
