Hi Kelly,

 

I haven't seen any other responses to your message, although I am sure it is
not for lack of interest.  The  current IPP Everywhere spec requires that
printers support DNS Service Discovery (Bonjour) and WS-Discovery. The
addition of WS-Discovery was at Microsoft's request and, since most network
printers already support both, this was easily agreed to. Indeed, most of
the network printers that I am aware of have supported these discovery
protocols as well as LDAP, SLP, and SSDP for well over five years now. It is
not clear to me that manufacturers would be anxious to add yet another
discovery protocol.

Google is implementing local discovery. There are many protocols that
implement local discovery (UPnP, Bonjour, SSDP, SLP, etc). Some of them are
more complex, some less. Usually they require device manufacturers
implementing HTTP server and XML parser.

We can also come up with a new very simple discovery protocol that will be
very easy to implement in any type of printer, and that will likely use JSON
(that we already use in cloud print communication).

Our goals is to reduce a pain associated with implementing local discovery
and drive it's adoption.

One of the existing protocols (which one?) or new simple Cloud Print
discovery?
Have they implemented any existing protocols already and how easy it was for
them?
