I suspect the color usage information is passed to the printer by PJL 
commands.
I'd suggest to capture a job ofiginating from a Win box and analyze the PJL 
statements at the beginning.
With that information, it sould be possible to either upgrade the socket 
backend accordingly or write a post monitor which pdates the PJL commands
(the latter may be a Perl or Python script, I think).
