I tried also to remove the compression of the individual PPD files (*.ppd instead of *.ppd.gz) in foomatic-db, but this does not help much. The sizes of the binary packages openprinting-ppds and openprinting-ppds-extra reduce by less than 10% (o-p: 3311892 -> 3129502, o-p-e: 18184504 -> 17508048) but the installed size on uncompressed file systems (hard disk installation) gets much bigger.
