Does anyone have any tips for printing black and white on the T220? We have a client who always wants black and white prints on a variety of substrates. Our prints always turn out a little green and the client is very picky. It usually works out in the end, but not without a lot of struggling. I'm sure part of the problem lays in the profiles that we have created, but I've had a hard time creating good profiles. Anyone else have simular problems?
