Why is it so important that the printer drivers is exactly adjusted to ink and paper?
If the printer driver does not know the paper you are printing on, it is possible that printouts show a colour cast, are pale or even too much ink is applied and tends to flow on the paper. For reproducing colors correctly, ink quantity and ink mixture must be adjusted exactly to the paper (and ink). Depending on the paper surface, inks behave very different when they are mixed as they also react with the paper coating. A resulting color cast must be known to the driver for beeing able to compensate it. The same applies to compatible inks of 3rd party manufacturers, which use different color pigments because of patent-protection.
