Some HP Printers use color ink to print black in Default Color mode due to incorrect PPDs

The default Printout Mode in the PPD for certain HP printers uses only the color cartridge, not the black ink cartridge. I discovered this because I have an HP DeskJet D2360 that was printing pink text despite having a new black cartridge. I found that by switching to grayscale mode the printer would correctly use the black ink cartridge and I would get black text. I took a look at the PPD and found that the following line was causing the problem.

'*FoomaticRIPOptionSetting PrintoutMode=Normal: "Quality=300ColorCMY"'

I was able to get the desired result, that is text printed with black ink and color used for color object by changing that line to the following.

'*FoomaticRIPOptionSetting PrintoutMode=Normal: "Quality=300ColorCMYK"'

I also changed the corresponding lines for High Quality and Draft modes.

I am running CUPS 1.4.4 on OpenSuse 11.3

I found all affected PPDS with the following bash commands from /usr/share/cups

'for i in `find | grep "\.ppd\.gz"`; do zcat $i | grep -q PrintoutMode.*CMY\"; if [ $? == 0 ]; then echo $i; fi; done > /home/jdmulloy/hp_ppd_list.txt'

'for i in `cat /home/jdmulloy/hp_ppd_list.txt`; do zcat $i | grep -q ColorCMYK; if [ $? == 0 ]; then echo $i; fi; done > /home/jdmulloy/hp_ppd_list2.txt'

The purpose of the second command is to filter out PPDs that don't contain the string ColorCMYK

I have attach the output in a separate file.
