Yes, to print or save an image of the chart, you can click the Save to Image button on the chart. See the Charting help for more detail. If you are using the image in a blog post or other publication, we kindly request that you cite Stock Rover as the source of the image.
If you want to print directly from the browser instead of using the Save Image icon, there are a couple of browser plugins that could help with the printing:
Firefox Plugin
Chrome Plugin
