However, I noticed at that bottom of the site page a tool bar with a printer icon on it. When I click on that icon, not the Safari print icon, there is a delay of a few seconds with a note to the effect the print is being prepared.
There's something else that I just noticed, after reading your post. If you hover the mouse over the print icon, a submenu appears with two choices. Click the one that says Print Page and then select your desired paper size from the popup menu (A4 appears to be the default but you can change it to Letter). Then, click Print and the rest happens as you describe.
I don't know why the page looks entirely different in Camino and Firefox.
