Hi, I had the same problem, now it's OK by killing the "smart" panel.
I killed it, but I don't know how to install the app:
if I go to
nothing happens on the screen.
However, may I suggest that these Samsung drivers work OK with AirPrint Activator 2.2b5 (to which I have no affiliation whatsoever). This handy and free tool allows you to Air-Print via iPhone / iPad without using the horrible Samsung Mobile Print Application.
