Hi (Again) :-)
Now i'v fixed DNS, connect iPad to the same subnet as printer and iPrint Alliances. Now i can scan for printers and choose the the right printer, but when i click "Print", then after some seconds it says "Printer is offline".
I've checked documentation and the only explanation is that it can't communicate with the iPrint Appliances.

Why?

iPrint Appliances 1.0.1
