有關意鐵網上購買事宜(購買一程MINI的車票)

我在意鐵網上購買一程MINI的車票...

收到確認的E-MAIL, 內含一個PDF檔. 檔案內容係TICKET DETAIL.

這個PDF當是否已是一張車票.

但這個當最下寫著:

ATTENTION: this payment receipt is not valid as a travel ticket as it relates to a ticketless purchase.To register your presence on board, please notify the ticket code (PNR) to the train personnel.

那我是否要到時在意大利火車站內輸入PNR CODE才列印正式車票才可上車,

如我想出發前先列印, 那又可以在站內那個地方PRINT?

THANKS~
