[Digikam-users] Printers with full Color Management

Yes, the basic drivers available (CUPS et all) do work in getting the data
off the computer and into the printer .... but color management really is
the problem.

I am using the HPLIP/CUPS driver that has no adjustment for the various
papers and trying to get the screen image to correctly be represented on
paper is a very hit and miss experience. The Color Management > Soft Proof
configuration in digiKam (at least using Windows ICCs) does not appear to be
having any effect .. at least with my printer.

I would be interested to know what others do to feel comfortable with this
