That's perfectly correct. However, from my observations in user forums,
driverless does not have the visibility amongst users one would like or
expect. One reason is that the GTK print dialog deals badly with IPP
printers.

A second reason is that a change in cups-browsed.conf is needed for a
printer to show up in the GTK dialog and users are unaware of this. A
consequence of both these infelicities is that users immediately seek a
driver solution. OTOH, IPP printers are immediately enumerated in Qt
apps and LibreOffice without cups-browsed.
