I know this thread is super old, but I've found MapQuest's "Static Map Web Service" to be helpful for tasks like this. You basically make a request and include a few parameters and the service will return a static JPEG. No screenshots, photo editors, etc., needed! Hopefully this will be helpful to someone.
In times like this I use a little program called printkey2000. You start it and it runs in your tray. Double click it, select Ctrl R, and it lets you draw a rectangle around the part of the screen you want to "grab." You then can save to .jpg format by giving it a name and selecting .jpg or simpler yet, put the .jpg on the end of the filename. It free for personal use. I have used it for years.
Note: you might have to adjust the time setting in the program to a longer time... Options/Define delay for rectangle. The initial 1 second is usually not enough for an old slow poke like myself.
