As some suppliers could have more than one PPD file for the same
printer, for example Foomatic PPDs can exist for one printer used with
different drivers, I suggest to add the driver or whatever is different
in the PPD after the model, separated by another dash. This should
optional but not required. In addition, there should be a directory
level between supplier and PPD for the language:

/usr/share/ppd/{supplier}/{lang}/{manufacturer}-{model}-{extra info}.ppd
/usr/share/ppd/{supplier}/{lang}/{manufacturer}-{model}.ppd

          extra-info can be the driver name or anything else which
          distiguishes PPDs for the same printer model. Spaces have
          to be replaced by underscores, as usual.

Examples:

/usr/share/ppd/foomatic/en/HP-LaserJet_4-hpijs.ppd
/usr/share/ppd/foomatic/en/HP-LaserJet_4-ljet4.ppd
/usr/share/ppd/foomatic/en/HP-LaserJet_4-opvp_pcl5e.ppd
/usr/share/ppd/HP/en/Hewlett_Packard-hp_color_LaserJet_4650.ppd
/usr/share/ppd/HP/de/Hewlett_Packard-hp_color_LaserJet_4650.ppd

Another question: What is "Linux Standards Base" really about? Only
LINUX or also BSD, Solaris, ...

In case of only Linux we could even require CUPS ...
