When you are viewing a web page you can save it (or at least the basic html or similar source text) to your local disk with the Menubar Edit->Save As... item. If the page you are viewing uses frames, then you will also be given the View->Save Frame As... option.
If the page uses a background image, then you can get and save that with the Menubar View->Save Background Image As... option.
But if what you really want is that glorious picture of the latest Ferrari, then RMB on the image will give you a drop-down menu with a Save Image As... option.
Be sure to respect the owners copyright, and ask for permission before using any pictures saved this way for anything other than your own viewing pleasure.
Printing a copy of the page you are viewing is easily done with the Menubar View->Print option, with Ctrl-P or with the Toolbar Print button.
