Hi there. great idea about memory cards, thanks!
Actually my printer came with EXTERNAL cartridges.. Some company here converts new printers to use external, refillable huge cartridges. They attach to the side of the printer and a ribbon hose goes inside to the printer heads. So, at least the ink is cheaper this way!

I have been researching this issue, and apparently there are some color managers for KDE (which I'm using).. I do not know which color manager KDE uses, and/or how to modify it.. I'm looking into it now.. -t

I solved the whole issue by downloading and purchasing Turboprint.. It's a GREAT print manager.
I just printed a picture at 9600 DPI, and the tones, the sharpness of the image is "weeping good" -- so good it makes you weep.
