Thank you for that information, that should make it a valid PPD file.
Still I don't understand where that format is defined in the
specification. If you feel comfortable with changing the parse to ignore
trailing nonsense without having a specification for that, please feel
free to go ahead and change the code in NSPrinter.m.
It should be enough to add
          [ppdData scanUpToCharactersFromSet: newlineSet
                                  intoString: NULL];

before the end of the loop in loadPPDAtPath:symbolValues:inclusionSet:
