I too just found my printer churning out 28 pages of mainly irrelevant stuff, including airfields I'm going nowhere near on my entered route. I used to be happy to print the next day's NOTAMs at home but not now, it'll bankrupt me.
I emailed my concerns and got a reply shortly afterwards. I suggest everyone else emails their own difficulties to NATS too. Let's try to get it changed asap before it's too late.
