How to enable AirPrint on iPod Touch after iOS 4.2 Upgrade? I have an iPod Touch (Model MC086FD) and upgraded to iOS 4.2.1 - all works fine. But I do not find the AirPrint Software on the iPod. Can I install it? How do I make my iPod print (emails etc.) when connected by WLAN?

I have a MacBook Pro with 10.6.6 Syncing with the iPod using iTunes 10.2.1. The printer is a Samsung CLX-3175FN connected by network.

I have no Print button in the share menu. Also I tried AirPrint Activator to enable for my network printer. Nothing helped.
My iPod touch is an 3. generation 8GB model (Model MC086FD).  As I found, Multitasking is needed to use AirPrint! But multitasking is not available for this model - even iOS 4.2 installed!
