wait so when i go to the airport tomorrow my ticket that i printed won't work?
It will. and it has nothing to do with being printed or not, it has to do with the validity of the ticket referenced in the the number you printed. Granted, they may think twice of canceling when you already checked in, but other than that it makes no difference.
Ps. If you're going, and staying for more than 2-3 days, pls pm your schedule for a DO.
