There are two printers that I can successfully print to in color from the XP half of my machine (an HP 4600 and an HP4550) but from the mandrake 10 half the test pages (and any other files) come out black and white.  Is there somewhere that I can let cups know that the printers are color or is there some other fix?  Any help would be appreciated.

I hadn't gotten a chance to try this until now, but I am running into the difficulty that the web interface doesn't give me any sort of color option anywhere and I am not having luck with the lpadmin command (have tried things such as "lpadmin -p printer -o ColorDevice=True", which gives no errors but doesn't change anything).  The lines of importance from my ppd file are the following, it seems:

If your printer(s) are really color printers, you certainly have the
wrong 
PPD. The statements you mentioned specify device properties, and as they
are not bracketed by *OpenUI and *CloseUI, there is no chaynce for user
selection.

To test, you could edit the PPD using a text editor and change these
lines to:
*ColorDevice: True
*DefaultColorSpace: CMYK

(or CMY if the printer uses only 3 color cartridges).
