How to adjust Black Contrast and slow Print Speed.

  • Go into the Command Line of the driver (direct command for printer or command to send to printer).
  • In the command line (with upper-case letters) type in:  +C_9 (space not underscore) and click send or execute. This will increase the black contrast giving a darker black print.
  • After you have sent or executed the command, delete the command out of the command line and type in (with upper-case letters) +V_9 (space not underscore) click send or execute. This command will slow the black print speed, for a more thorough and consistent K-panel print.
