Without getting in to the question of whether it is a misuse of SNMP
or not, yes, there definitely are products that do printer discovery
using the response to SNMP (over IP and/or IPX) MIB queries.
Directory systems, at this point, are inconsistent, often not present,
and sometimes not under the control of those concerned with getting
printers up and running. Printer companies attempt to address the
needs and desires of their customers, perhaps at the expense of
architectural purity or even good engineering practice. That is how
they stay in business (those that do).

I think you may have misunderstood what Harry meant by "Printer discovery".
In this context, "discovery" implies finding out what the specifically
targeted device is capable of supporting, rather than which devices are
available on the network, etc.
