command line

For more advanced user, 'scrot' is a command line tool that takes screenshot of either fullscreen, current window or selection area. You can bind this command to the printscreen key if you visit System > Hardware > Keyboard Shortcut and scroll down to the custom keybinds. There you will see the Printscreen function and can edit it to execute one of those:

# Create a screenshot of the entire screen in your home directory with a datetime stamp
scrot ~/%y%m%d_%H%M.png

# Create a screenshot of the current window in your home directory
scrot -ub ~/%y%m%d_%H%M.png

# Opens a selection tool to select the area to screenshot
scrot -s ~/%y%m%d_%H%M.png

For advanced info on scrot type man scrot in a terminal.
