If you go on Disney's website, look at the top line that says Parks & Tickets, go under each individual park, over on the righthand side right underneath where it lists the parks hours for the day, there should be a line that says download printable map. Click on that and you can print the map.
I also recommend going to easywdw.com and over on the righthand side of his site, click on where it says "cheat sheets" and it will bring up each park as a printable map. I like his maps the best because the rides are labeled and there aren't ten million symbols like on the official park map. On our last trip, I printed easywdw's maps, circled the rides I had FP+ for and the resturants I had ADR's for, wrote the time next to it and then folded it up and carried it in my pocket. It was a very simple way to keep track of everything in case my phone died.
