Hello Mike, 'tis a nice day today.

        My apologies here for mistyping this acronym, it is CMYK and
 stands for Cyan-Magenta-Yellow-Black ( if I got this right this time ).
 I just checked and that is proper, ref: Canon User's manual.

        And indeed, it stands for a colour printing mode. I was told
 that the USB port is faster than the LPT1 regardless of using
 black/white or colour mode, for the same printer ! I have a Lexmark Z32
 here that has both connectors and obviously, it is using the USB port.
