The original purpose of IPP was to replace LPD, and LPD handled
a few printer administration issues as well as the mundane print
and cancel job type operations.
Whether or not to address administration issues in IPP has been
an ongoing battle. IMHO *not* providing support for operations
and features needed beyond the printer will hurt IPP in the
long run. Network printing has always been a pain, and
providing a single, vendor-neutral protocol for all printing
stuff is the only way to fix that.
Will printer manufacturers include driver download support in
their products? I doubt it - too many driver revs, languages,
and OS's to fit in limited ROM/flash memory. More likely this
extension will be used by IPP-capable printing systems on desktop
or server machines.
