Printing in NUS libraries are not free unless you are a SOC student. SOC students have free print quota that can be used to print only within the SOC faculty. That said, Central Library allows you to print your lecture notes (note: you don’t need to print lecture notes for lectures unless specifically mandated by the lecturer) and project reports with a really ‘highly advanced’ system that only accepts CashCard (sigh). There’s also a book-copy center .. err.. I mean photocopy and binding room in the Central library when you can photocopy and pay with CashCard and ezLink (for photocopying only). Rates are 4.5 cents per page for printing and 3 cents for photocopying (source). You can also photocopy and bind at CO-OP outlets with cash / NETS payments. Other NUS libraries may also have facilities to allow you to print/bind, but I have not tried them personally. All libraries have self-service photocopy machines requiring payment using CashCards. After the closing hours of about 5pm and 6pm
