We've had the check in people at BW, WL print boarding passes, and the Guest Service office in Epcot let us print our own on their computer. It shouldn't be a problem at the desk at OKW! Ask at check in so you can relax regarding the "problem."
We always bring our lap top and check in online. I don't bother printing the boarding pass until I get to the airport. With Southwest I just go to the computer kiosk and enter my ticketless travel numbers and it prints my boarding passes.
