Make sure the driver settings do not return to the default before the actual printiong happens. The Z drivers tend to do so. Best way is to create a printing shortcut in the driver that has Application Color management on + color printing. Select that shortcut and select the right media preset, that way it usually sticks better than changing the CM settings per job.
Use Relative color metric + BPC or Perceptual rendering in Photoshop.
Calibrate the monitor on 120 candles or as low as 100 candles depending on what your monitor can handle and the studio light + print viewing light conditions.
Use a viewing light near 5000 K.
