[Design] Disabling printing

[Philippe Bossut]

Hi,

Printing in Chandler is disastrous and overhauling it right now seems to 
be way too late for Preview. Since few people have been championing this 
feature and since it hasn't received any attention at all from anyone, 
I'm proposing to simply disable it from Chandler for Preview.

I just logged a bug on this: 
https://bugzilla.osafoundation.org/show_bug.cgi?id=8137

Thoughts?
