AirPrint and Samsung printers (ML2955DW)

Hello,

I have a Samsung laser printer 2955DW. I have installed it on my wifi network and it works nicely with my MacBook: I can print !

But I cannot use iPad: the printer is not found by AirPrint.

Note that the printer is supposed to be AirPrint compatible (it is listed in the Apple's list on support webpages).

Somebody can help me ?

Thanks in advance !
