Digital BW, The Print

Hi Bob

Apparently not.  My understanding is it doesn't use the ICC profile.  See
here for example:

They have simply made the printer (within tolerances) linear L* from white
point to black point at least for the Darker setting.  I assume the
adjustment sliders/settings introduce changes to linearity/gamma and black
and white points but I do not play with these.  I prefer to get it right on
screen and don't do any adjustment in the driver controls.  At any rate
though I use Roy's QTR create ICC profile to profile the luminance of the
AB&W and use PS to convert to this profile on the fly before sending the
(adjusted) file values to the printer.  The output is just fantastic.
Linear L* output has all the problems we have debated under the QTR banner
for the last couple of years (ie gamma shift).
