Different vendors use slightly terms to describe the existance of PDF
interpreters on their machines. They also implement it in slightly
different ways but I haven't quite worked out whether they all
ultimately use the Adobe PDF Print Engine (APPE) in some way.

Over the past ten years PDF interpreters have moved out of the high-end
market into the mass consumer market. The HP LaserJet Pro M402dn at less
than 200 Euro, for example.

The importance for Debian is that the day when there are no longer any
proprietary printer languages exclusive for a printer is upon us. Couple
that with IPP Everywhere printers and we are free. Fixating on printer
drivers (already deprecated in CUPS) will be a thing of the past.
