[Bug 52017] Re: changing settings (like paper size) have no effect in CUPS

[Chris Burgan]

I can confirm a very similar problem however this was in Edgy and the
printer being used was a HP Deskjet 940C.

 The problem was that by using: System -> Administration -> Printing
menu to go in and change the printer properties, in this case default
print type from normal to normal grayscale would have no effect in the
printer's ppd file or anywhere else for that matter... resulting in the
printer always printing in color. By manually changing the
"*DefaultPrintoutMode" from "Normal" to "Normal.Gray" we were able to
create a workaround.
