I purchased a ticket online from them two years ago. I don't remember if I printed the ticket online from their web site after I paid for the ticket or if they emailed the ticket to me but I know it was either one or the other because I remember having to change the settings on my printer. Below is from the email that was sent to me after I signed up for an account:

"If you book before 4 p.m. your travel documents will usually arrive by post within two working days (Mon-Fri). On payment of EUR 3.50 P&P, your ticket will definitely be delivered to your address by post in good time before the journey begins. You can print out reservations yourself up to ten minutes before departure."

Where they say you can print out reservations yourself up to ten minutes before departure I think they are talking about the ticket.
