You can buy it online and print it at home through www.swissrailways.com/ en (see here for other options). Unless you mean the 7th of April (tomorrow). In that case you're too late to buy online as it takes 1-3 working days to receive the pass through e-mail. You'd best go to a staffed desk at the Lucerne train station. As far as I know it won't be open at 11:00 PM and 6:00 AM. An hour later it should be open.
