[cups] Windows bypasses cups drivers

[Alex Korobkin]

Maarten,
It is unclear if you uploaded printer-specific driver to the client or to
the server.

If you uploaded manufacturer-provided Windows drivers to the printserver as
explained here
https://wiki.samba.org/index.php/Samba_as_a_print_server#Uploading_printer_drivers_for_Point.27n.27Print_driver_installation
you can set the default settings to grayscale printing (Advanced > Printing
defaults), and every new client will have that set by default.
