(The image here is a jpg - don't mistake it for the map itself)
Above is a screenshot I took with Grab. If you have a Mac it has it for sure.
Open the map in a browser and size it to fit your screen ~
Take Screen Shots with your Mac's program Grab (do a spotlight search "Grab" to find it)
Hold down shift + command + A and then you can drag a square and capture a screen shot and save it to your desktop as a tiff. (If you open with the application Preview you can "save as" and make it a jpg if that's better for you too.)
Then you can print your tiff or jpg with a printer.
Use the Grab application. It is on your Mac for sure.
Best and love
