"...when I print the paper ticket from the kiosk."
Simply printing the ticket will not get you the points. The conductor must scan either a paper ticket or eticket on your smart phone. The conductor may also check you in manually by name.

Paper or electronic, my points usually post within 5 days of the actual travel. I usually use paper as its easier to pull out of my pocket than bring it up on my phone (unless I do that ahead of time).
