No, I didn't mean print right now!

Can you tell me why clicking this Excel toolbar icon:

and choosing this dropdown menu item:

do not perform the same action?

Despite having the same icon the two have different effects. Clicking the toolbar icon prints your page right now; choosing the menu item brings up the Print dialog. Speaking of which: why can't I choose 'Fit to Page' from the Print dialog? I have to go into 'Page Setup' which has always struck me as a stupid design for Microsoft products. (But I use them -- and most office produces -- so infrequently that I'm perfectly willing to change my mind on this.)
