You mean the map you see as default on osm.org?
Sure, you can.
Just follow the instructions: https://www.openstreetmap.org/copyright

There are options on the right hand menu (square with arrow heading to bottom right) on the main page to allow you to download rendered maps in various formats, which should generally be better options than simply screen grabbing.

These include SVG, which will allow you to create much higher quality printouts than the bitmaps that you get from screengraps. You will still have to add the copyright and licence information manually.
