All day in the dealer room, the printer kept connecting-then-dropping over and over again, meaning it could not succeed at any task that inolved transferring data-- meaning, it could not succeed at any task. Later in the room, both printer and iPad could see the network beautifully, but neither could see each other. Finally, after 45 minutes on the phone w/ the Marriott help desk guys, the conclusion was reached that, "I dunno, I can't see any reason why it's not working. Some sort of problem with the Client Isolation settings, I guess."
To his credit, the Marriott help desk guy really was trying. And he did eventually enable us to proceed by making it possible for sirfox's laptop to talk to the printer.
Hooray! ...What do you mean you're out of cyan? *facepalm*
Net result: After fighting with it all day, we managed to scan two pictures with it. Hail the conquering heroes.
Anyhow! That's all behind me now. We're headed downstairs to have breakfast with T'Chall, and from there it's checkout and back to the dealer room for what I'm hoping will be a more prosperous day. Then tonight... home! Yay. I miss laurie_robey and mah kitties!
