The attached debdiff for cups fixes a nasty bug in Bookworm.
If the PPD file for a printer has a ColorModel option and the only choice
for printing in color is not named RGB but CMYK instead, the printer
cannot be made printing in color with intuitive methods, usually
by selecting the color choice in the print dialog.
The fix was already applied in Unstable/Testing and also uploaded
to Ubuntu-Lunar and seems to work as expected.
