Hi Gary,
I'm using Windows 8, the old printer worked fine with this operating system. I'm sure it's the ink, either the ink or printer. I have been wanting to try out their MAC profile, to double check it's not the profile, but the instructions that I've been given for the MAC don't match my dad's computer (a MAC book pro version 10.10 'I think' Yeo... something). CIE's user guide on how to use the MAC profile, doesn't seem to match the kind of MAC that my dad has. So I can't even try a different profile to double check .
