Printing from NINJa stations requires authentication through the University Network. To authenticate you must have a UNI (University Network ID) and Password.
Visitors may obtain a UNI and password at the Library Information Office (Butler Library, room 201). Please see the library access information page for more information about visitor privileges.
NINJa printers are networked to Library Netstations throughout the Libraries. After making a print request at a Netstation, you must approach the NINJa printing terminal, choose the relevant print job from those waiting in the print queue, and enter your UNI and password. Page allowances apply to NINJa printing. For more information about printing quotas: http://www.columbia.edu/acis/facilities/printers/quota.html
