Since it wasn't clear, "bnjp://" over 8611 is the "bonjour"
protocol
(Apple's implementation of the Zeroconf protocol).
No it is not Bonjour
related. BJNP is the Canon Inkjet printing
protocol. Cups-bjnp implements this protocol to enabler network printing
on Canon Inkjet printers. Sane implements it (on port 8612) for scanning
over IP-networks. Now it is true that Canon printers often use Zeroconf
for advertising their capabilities, so cups-bjnp could theoretically use
it to find printers. It however uses UDP broadcasts to find the printers
on the local network. Implementing zeroconf in cups-bjnp is somewhere
low on my TODO list (I wrote cups-bjnp) as nobody has asked for it and I
have no use for it myself.
