I can recommend two websites where you can print maps on your own. This should be sufficient for safety-backup purposes. These maps are up to date and for free!

norgeskart.no
here you can print a 12 x A4-sheet area in 1:25000 or 1:50000 scale [to do so you have to search ('søk') a place, say Kautokeino, first. Then click on 'Lag Turkart' to choose an area. ] Edit: Just noticed that Norgeskart also has an English menu (click on the menu icon; then you can choose the language at the bottom)

kartutskrift.no
This is more customizable, but probably a bit more complicated. You can choose the scale and the dpi resolution, and you may create A3-files. However, you can only print one sheet at once which may take a while,
Generally, I prefer norgeskart, but kartutskript is useful for higer-scale maps, for example an area overview.
