If you have booked a Ticket on Departure, you will need to print your ticket from a self-service machine at the station before you board the train.
Eurostar tickets can be printed from self-service machines in any Eurostar terminal in the UK. French rail tickets can be printed from any one of 1,400 self-service machines in stations across the French SNCF rail network.
If you are travelling on both Eurostar and French SNCF services you will need to use Eurostar machines in the UK and SNCF machines in France to print your tickets.
