Tried to print out a boarding pass for US Airway. It got through all of the info OK until it pulled up a window that showed "retrieving boarding pass". It never got past that. I know that flash doesn't work on iPad but I don't know if that is the problem or not. Is there some app etc that I should be using? I have my computer and iPad set up so I can use WePrint and that part worked fine on previous document.
