Bee,
I'm sorry, but that does not look correct.
If you look at the bottom there on your screen shot, you will see the "1" is highlighted. That is the first page of four pages of the post.
I know it says 5 of 5, that is because a print page is different than a web page. Web pages are longer than the usual 11". You are only printing page ONE of the discussion.
The last Post you are printing is by "jcbigears"
BUT, the LAST POST of the entire DISCUSSION is on "web" page number 4:
https://discussions.apple.com/thread/3190227?start=45&tstart=0
As you can see, the LAST POST of the entire DISCUSSION is by "ZX48" not "jcbigears" and, it is on PAGE 4 of the discussion (not page 5).
Page 5 of 5 is referring to the PRINTED pages, not the DISCUSSION pages.
So you see, you are unable to print an ENTIRE DISCUSSION, too.
** laverne\'s mom -- I do not believe it is your printer. It is something the Discussions does not support.
