I was attracted by this idea and it gave me pause for
thought. Leaving aside printers that include a network
interface, the IPP-over-USB standard applies to a
non-network-capable printer.
The specs require IPP (put in firmware, I suppose) and
DNS-SD discovery (again in firmware). Little extra cost?
AFAICT, a networking stack is not specified. Why should
it be for an isolated machine?
Some USB-only printers and standalone USB scanners do
implement IPP-over-USB. But a vendor never advertises
this or explains why.
