They are located in Sherman Fairchild Library (4 machines), Millikan 9th floor, Dabney 1st floor, Cahill, and Geology main room. From any printer, swipe your card, enter your access.caltech credentials, or enter your PaperCut pin number, and you will see a list of all pending print jobs. You can then choose to either print or cancel the job. Don’t forget to log out when finished using the printer – you will be logged out automatically after about 60 seconds with no activity.
