Given a printer setup with a CUPS server containing a PPD with a
non-standard Grey ColorModel (e.g. KGray) and a standard color option (e.g.
RGB), CUPS advertises the printer with print-color-mode-supported =
{color,monochrome}.  However, print jobs indicating a print-color-mode do
not respect the attribute.

Is print-color-mode supported for printers using a ColorModel that is not
'Gray'?
