^^ You can, but there's a limit on the free on-line map-generating tools, and none of them will produce an all-Europe map. I don't think there's a technical reason why you couldn't have an all-Europe OSM map - I just couldn't find anywhere to download one, or any way to create one. In the end, I decided that spending 66 quid was better than wasting any more time trying to avoid having to.
