My last step in moving away from Photoshop was to sort out the colour management system in PixInsight to produce reasonable prints. It wasn't too difficult once I got down to looking at it. For calibration of monitor and printer I used this device
http://www.colormunki.com/ . It's an all-in-one monitor, projector and printer calibrator; simple to use and works very well on the trial images I have printed. So now I have a complete PI workflow from the time I load the raw images to printing them.
Still have to use Maxim for camera control.
