One of the great things about most airlines is that they realize that most of their fliers will probably not have a printer available to print out boarding passes when they are ready to check-in 24hours in advance like SWA and COA. A number of the airlines like COA are now working with paperless Boarding passes that eliminate the need to even get them from the kiosks. These work with your Cell phones and PDAs that are internet capable. unfortunately SWA is not there yet and may never be.
Just wanted to add that you can do online check-in and print boarding passes at guest services at any of the Disney parks. Just give them your confirmation # and they will print them out.
