How do I find out if the color space of an image is sRGB/AdobeRGB, etc.?

Is there a simple utility for this, or a way to easily find out the color space? I need this for printing, because the printer (OKIC532) has been rendering colors strangely lately with a blue shift, sometimes green. I know that CMS - color management system is a science for insider wise heads and with experience. I keep coming back to it, especially when I least need to deal with it. After all, I would be interested in advice, experience on how to tackle this at home. There is a lot on the net, but I lack a simple and usable procedure.

Thanks for the insights
