I'm not sure of the details. Here is the background: The Printer Working Group is engaged in an effort called IPP Everywhere¹. The goal is to have "driverless" printing by having a small common set of imaging standards in printers, and for the printer capabilities to be inspected using IPP. There is no need for PPDs in this vision of how things will work in the glorious future, "when" all printers support IPP Everywhere. The way I expect it to work in CUPS 1.6 is that the concept of PPDs disappears as far as clients to CUPS are concerned, but that it will still use PPDs internally for existing printers that do not support IPP Everywhere (that is to say, all of them right now). In other words, I think the direction it is going is to make PPDs an implementation detail of CUPS. How that will work in practice I don't know yet.
