I am running 12.04 and Firefox just upgraded to FF 29.  I have been able 
to print pdf's from FF with no problems.  If it makes a difference I am 
printing to a Samsung CLX-3160FN networked printer and and old HP 
Laserjet on a print server.

I did notice that if you have multiple tabs open and try to print, the 
print preview takes over the whole FF window and you cannot access your 
other opened tabs until you close print preview.  I had a quick look in 
about:config and there is a setting for printing from print preview, but 
I have not had a chance to experiment with it.
