Is there any site that provides city maps adapted to be printed at home to an A4?

I'm traveling to a country where internet access is hard to get and it would be very useful to carry those maps for the 7-8 cities that I will be visiting. For instance, to beforehand mark the places I want to see or where my hotel is.

There are plenty of sites that offer high resolution maps to print as posters, but I need just some simple schema of the city.

Note: I am travelling to Cuba but a general answer is okay.
