Panel (or the value set during installation if you have
not used the control panel before).
/? Displays help about using the DJCP command.
/H Displays help about using the DJCP command.
/M Changes the colors used in the Control Panel to be
compatible with monochrome displays.
Example: To select the printer on parallel port 2 (lpt2),
type "DJCP /P2" at the DOS (C:\>) prompt.
