please use the same method for both, which means the more portable one.
given QPrinter::GrayScale is unreliable for the preview, we should use
the CSS thing:
-webkit-filter: grayscale(1);

like i hinted in the email to Dirk, different greyscale methods can
use a different luminosity distribution, while we *do want* both the
preview and actual greyscale print to look the same, as much as
possible, that is.
