What is Xfce4 Screenshooter?
This application allows you to capture the entire screen, the active window or a selected region. You can set the delay that elapses before the screenshot is taken and the action that will be done with the screenshot: save it to a PNG file, copy it to the clipboard, open it using another application, set a custom action, or host it on Imgur, a free online image hosting service.

Said about Xfce4 Screenshooter as an alternative
Built into Xfce (which I use) and performs all the Snipping Tool functions that I know of.
