Thanks for replying.

There is no "ink saver" option or the like and DPI is set to 600.
I can't find any colour profile in windows and I don't know where to look for 
similar file in Fedora.

However, I find in the printing settings values like Saturation = 100%, Hue 
adjustment = 0 and Gamma = 1000. Tweaking these values does change the colour 
impression somewhat but I haven't found the "correct" combination. So I assume 
I'll have to continue tweaking until I am satisfied. I wish there were a 
description on how to.
