Hi George,
I was pointing this out because I don't use the IPP Anywhere
interface, and cups has never supplied drivers for my printer, I've had to
always the Epson supplied driver to enable printing in Linux. This was just
an observation with, when adding a printer, cups shows me two entries under
the "Discovered Network Printer" section, one for IPP Anywhere and one for
the "Driverless" option, where the IPP Anywhere shows two separate driver
definitions for cups drivers and the driverless option, whereas the
"Driverless" selection displays all drivers in the one list with the
driverless driver listed first and all the cups drivers then listed in
alphabetical order.
I wonder if we are in a transitional phase where legacy CUPS is mixing with
IPP. Some manufacturers may provide legacy support in their printers when
they add IPP,
but (until Apple changes AirPrint), most manufacturers' networked printers
will provide IPP because they want Apple AirPrint to work for customers
using IOS.
