Printing from iOS has been requested a long time ago.
Up until recently I used dtPlugins to do it but they no longer work, so I wrote the necessary declares to print from a MobileHTMLViewer and MobileTextArea.
Printing will be available in @Jason_King 's iOSKit as soon as the pull request is accepted.
If you have specific printing features you need, just let me know and I can update the code.
