So how is that any different from the rest of the game? It's hard to believe that anything would be operational after 200 years of neglect, including the guns and ammo you find. It's pretty amazing for instance that the Metro tunnels have all those lights that have never burnt out in all that time, not to mention hydro in order to make them work in the first place. And where is all that running water in the various sinks, toilets etc. coming from? The pumps that provide the pressure to make them work should have broken down a long time ago with no one looking after them.
i always figured that the brotherhood of steel simply repaired the existing pre-war power stations in the fallout world because it was far more convenient than trying to build an entire new generator for their bases and citadel, the side effect was all other locations got power as well. the waterworks were likely repaired for similar reasons
i believe the game itself has a few cut/uncut references to things like that, such as old olney powerworks
as for the printing press requiring maintenance, thats only really a problem if the press itself is used regularly, after the bombs fell the press more or less stopped requiring it.
but if you actually go to hubris comics and try starting the press it has a corpse jamming it that you have to remove through a cut event
