I am new and need to study the maps. Is there a good place to download them? All 1v1 maps. Just need decent enough resolution to print them out.
The teamliquid.net wiki has images of all the maps. The images have quite high resolution, so that all important details should be visible.
If you want to create your own pictures, you can also open the maps in the map editor and then export them as an image using Data -> Export Map Image.
You can open maps directly from battle.net and you can choose what details you want included in the exported image, so you can create your own custom images without too much trouble.
There are a few of them here. Not the best resolution, but better than nothing.
