Public bug reported:

Binary package hint: foomatic-db

The /usr/share/ppd directory uses a lot of disk space.

All the ppd files are currently compressed by using gzip.

I think that using lzma would decrease the disk space used as well as
improve the  decompression speed.

Below is a comparaison for the file 
/usr/share/ppd/openprinting/KONICA_MINOLTA/KO1050UX.ppd.gz:
-----
j...@j-desktop:~$ du KO1050UX.ppd*
256     KO1050UX.ppd
24      KO1050UX.ppd.gz

j...@j-desktop:~$ time { for i in {0..999} ; do unlzma -c KO1050UX.ppd.lzma 
>/dev/null ; done }
