Photoshop images are faded

I have never had any problems printing images from photoshop but two days ago something changed and now everything prints faded. This problem happens when using either of my printers but only if I print images from photoshop. Other images printed on my mac are fine.

I have reinstalled the printers and photoshop but no change. I am wondering if some of the presets have changed but I cant find anything to help me and I dont really know what the setting should be as I am not a very experienced user - does anyone have any suggestions?
