This is equally a question about Epson iPrint. I am using Numbers on iPad 2 with iOS 5.0.1 and am trying to print to our wireless Epson SX435W. The SX435W supports wireless printing for the iPad/iPhone/iPod using the Epson iPrint app. Consequently, when trying to print directly from Numbers, the printer does not appear as an AirPrint printer. iPrint supports printing from Photos (the photo album) or "Saved Documents". However, Numbers appears to have no facility for saving documents and the iPrint Documents folder is empty. The only other option would be to use online storage but there is nothing in common here as Numbers supports iWork.com, iDisk, and WebDav, whereas iPrint supports Evernote, Google Docs, Dropbox, and Box.
