Another fix, if your friend is using Photoshop, would be (already assuming that the monitor has been calibrated) -
Make sure that (in the print dialogue box) that Photoshop is handling the colours and not the printer.
Ensure the printer profile is for the correct make and type of paper. If you haven't got the profile, go to the paper manufactures website and download it.
Duplicate the layer.
Change blend mode to screen.
Change opacity to 20% (a few test prints will indicate if you need to go higher or lower).
Once you're happy with that setting, you could if you wish, create an action within Photoshop to automate the process.
