Making a HP 4650 default to printing black & white

[Torkil Svensgaard]

Hi

I'm trying to get our HP Color LaserJet 4650 to default to printing in 
black and white instead of color, while still giving the users the 
option of enabling color for particular jobs but I seem to be stuck.

In the PPD file I have tried this:

*DefaultColorSpace:     Gray
*DefaultColorModel: Gray

Neither makes any difference, the print preference GUI in Windows XP 
still uses color as default instead of black & white.

Any ideas?
