    Peter, I agree with all your points and have an interest in this topic. I
    recommend the eventual creation of a LOC@PWG.org list. Unfortunately, I
    won't be able to attend in Toronto.

    I hope most of you have seen some of the conversations that have been
    on regarding the advertisement of Printers and Print Services in the
    Srvloc-discuss group on sourceforge. I believe some has been forwarded to
    the IPP list. I am hoping the PWG can take up the issue of printer

    The advertisement of printers and of their channels (i.e. access protocols
    and points) should be of interest across our companies. It would be
    mutually beneficial to codify the use of service advertisement for
    A number of technologies exist such as SLP, LDAP, JNDI and SSDP.

    We have templates for some of these however the mapping between them may
    have some complications. We have an existing PWG straw man proposal on
    SSDP would be used in an existing SSDP environment. We should have
    recommendations on how printers make use of all the advertisement
    technologies to insure interoperability in heterogeneous environments.

    There are many optional attributes that may be of general benefit to
    discovery and might be useful to populate. Another issue is how many
    channels should a printer advertise and what the exact mechanism should be
    to make the associated channels of the printer visible. Some solutions
    require the ability to identify multiple advertisements of a printer
    as belonging to the same device.

    The outcome of this discussion should be a PWG document with
    regarding service advertising. The issues that we uncover/address can be
    fed back into other standards bodies addressing service advertising. (I
    would hope the path we take would not be printer specific and can be

    I propose that this conversation be held on the IPP@pwg.org list
    Please do not respond on the PWG-ANNOUNCE@pwg.org list

    I hope that we can find some time in Toronto to discuss this work.
