AFAIK *all* printer manager programs (CUPS and whatever Windows's is 
called, and some of the weird proprietary things used elsewhere; but 
probably not printer managers on Android) use PPDs to define the 
capabilities of each printer.

The fact that PPDs are written in the Postscript language is a 
historical artifact — it does not mean that any given printer actually 
supports Postscript as a PDL.

hplip should install all the needed dependencies. It has done so each 
time I've installed it, but your system may have different requirements.
