I tried to use the machine, since I can't really speak Italian.
I used the British language mode.
Then I pressed print/change reservation, and once it had my ticket on the screen, there was no option to print. Only to change the reservation.
There was another menu item that said collect ticket, but once I entered all the ticket info, it gave me a weird warning. Something like:
"Warning: sale ticket not allowed without train." I didn't understand it :(
My train ticket is for a month from now, but I wanted to figure this out now, since I booked a lot of train tickets in advance. Can anyone help me?
