Oh, I forgot. For the xerox 7400 there is a trick to use the same color
drums twice or even three times. This could reduce this cost at 1/2 or 1/3.
If you need info, please send me an email (jir_2008(a)yahoo.gr). Having 4
drums is an advantage, otherwise the cost would be much higher. This printer
raises slightly the 3 color drums when it prints b/w, using only the black
drum (in this case it insulates totaly the three other colors). Not all
color laser printers does this.

Not a driver but certainly better than jpegging the whole thing:
print to PDF (every DTP app can do this), either directly or using a
virtual printer.

Most prepress workflow uses PDF these days.

Then you can use Acrobat.

If you can output your text pages using your B/W option to PDF, you
can then join them into one file with the colour cover using Acrobat.

Or "Quite A Box Of Tricks" from http://www.quite.com/box/index.htm
is an Acrobat plugin that can convert all colours to greyscale,
amongst other things.

There is another solution using PrintMulti.
It is a print processor which can act as a virtual printer with the
possibility to print a single job to multiple printers with many options.
In your case the job will be printed twice to the same printer. First job
only containing the first page in color. Second job the other pages in b/w.
Since this result in two different print jobs you might have problems with
your finishing (try using file save device modes or contact me if you need a
change in PrintMulti).
PrintMulti is free for all client OS. A configuration involving a virtual
printer "FirstColorPagePrinter" could look like this:

[FirstColorPagePrinter]
Active=1
Action1=Print;FirstColor
Action2=Print;OtherBW

[FirstColor]
Printer=YourLocalOrNetworkPrinter
FirstPage=1
LastPage=1
Color=1

[OtherBW]
Printer=YourLocalOrNetworkPrinter
FirstPage=2
Color=0
DeviceMode1=... for file saved device mode using a finishing option.
