Hiya canonman,
The best bet is to right-click the link ecart4_gsg.pdf and select 'save as' or 'save link as' to download the whole guide to your machine, rather than having to wait for it to load up online whenever you want to refer to it.
You would then just print it out by opening it and pressing 'print' (if that's available) or the printer icon in the menu/toolbar. Or before you open it, you can just right-click the file and select 'Print' from the right-click menu options.
