# Correct or remove non-working PPDs:
# Several HP PPDs contain "600x600x2dpi" which is not allowed
# according to the Adobe PPD specification section 5.9
# and which can be simply replaced by "600x1200dpi"
# because "600x1200dpi" is not used elsewhere in the PPD.
# Some PPDs contain a "*cupsFilter: ... hppostprocessing" line
# which cannot work because there is no "hppostprocessing" filter.
# Some PPDs contain "1284DeviceId" which must be "1284DeviceID".
