It's very much worth your while to open an IRCTC account so you can make bookings online. It's India, so the process is a hassle, but then lining up at the station ticket window is far more a hassle. Note carefully all the rules, including a limit if six journeys booked per calendar month.
No need to find a printer: the emailed ticket on your phone is enough.
