   Foomatic is fixed now. #2 is implemented. Now for getting a PPD for a 
   printer driver combo only one of printer and driver XML file is enough.

   Note that if the printer XML file is missing it cannot be determined 
   whether the printer is monochrome or color. I let all PPDs tell that the 
   printer is color in such a case, as color input data can always be 
   turned to grayscale by Ghostscript, so if a program chooses to output bw 
   or color based on the PPD this way all printers will work correctly.

   Get the fixed foomatic-db-engine from the BZR repository. I will also do 
   a release soon.

The Gutenprint data does include sufficient information to determine
whether the printer supports color or not.
