One thing that is interesting, if I use KDE's system settings to add a printer, and I select the Epson ET3700 Series network printer entry which uses IPP Anywhere, when I'm prompted for the driver I get offered two Epson categories (Epson and EPSON), the second category has the driverless driver and the first category has all the cups supplied drivers, of which there isn't one for the printer I have. I've had the printer for several years, but I guess it is still too new for cups to support.

OpenPrinting CUPS
The current standards-based, open source printing system developed by OpenPrinting for Linux® and other Unix®-like operating systems. CUPS uses IPP Everywhere™ to support printing to local and network printers.
I doubt anyone will be working on legacy CUPS drivers for printers that support IPP/AirPrint/<other verndors' IPP implemenations>.
