what Michael Sweet wrote is how "*ColorDevice: False" in a PPD
is meant to work in theory but as you found out in practice
  "In theory, theory and practice are the same.
   In practice, they are not."

I think I vaguely remember that stuff never worked reliably
in practice which is the reason behind why I wrote in
... using a monochrome PCL driver is probably the best way
to enforce fast monochrome-only printing.
