I recently tried to upgrade my MacBook to Mountain Lion and without going into the gory details, that caused some kind of hard drive crash and I had to have my hard drive reformatted, etc. Now I am back to OS X 10.6.8 and Safari 5.1.7 but since the reformatting (and installing Adobe v. 11 something) I can't print from Safari without downloading the file. My default .pdf reader is preview. Prior to this Mountain Lion fiasco, anything would print from any application when ever I wanted to which ever of three printers I desired.
