Checking, it seems ippfind could be built without avahi (haven't tried),
but in pkgsrc currently ippfind will only be built on Darwin, or with
the avahi option which is off by default.

On another front, I see in cups-filters 1.28.5:

       - driverless: Reduce ippfind calls by "driverless" and
         "driverless-fax"called by CUPS. Let "driverless list" list
         both print and fax PPDs and "driverless-fax list" do
         nothing.

which means an update may help a bit.


I am just noting why OP's log couldn't find ippfind. It ought to be possible to
still set PPD for an HP and print successfully...


Cheers,
