Color Matching Options
The Color Matching options in the PCL driver can be used to help
match your printed colors to the ones displayed on your monitor.
The PCL driver color matching options are found on the Color tab in
the driver:
NOTE
The PCL driver’s color options are only designed to
work with RGB data.
If you are printing CMYK data, we recommend you use
the Postscript emulation driver (optional on Model
C5400).
