SAI> Do you envision a "cost-per-page" attribute that is set to some
SAI> value like "$0.32" or some set of attributes that are queried and
SAI> evaluated and some cost per page number is generated?
SAI> If you envision the later then I say that this is beyond the scope
SAI> of IPP
RKD> I envision a cost-per-page attribute that is set when printer
RKD is configured.

>>> answer: The name service needs to be able to tell a user that

SAI> I agree that the name service should NOT have relatively dynamic
SAI> attributes. media-ready should not be in the directory. However,
SAI> I don't agree that we should put what a tray is supposed to have
SAI> in the directory. What is a standard letter tray supposed to have?
SAI> All media types that fit letter size???
RKD> If you don't do this, how can I ask the question "Can I print
RKD> tranparencies on this printer?" On the shared printers we use
RKD> around here one tray is often set up with transparencies in it.
RKD> It would be nice if I knew at least that an adminsitrator/operator
RKD> had configured the printer this way. Otherwise, my only recourse
RKD> is to walk down the hallway and look at the printer.

>> answer: We need a "notification-methods" attribute.
<SAI> I disagree. I thought that we decided the methods would be
<SAI> embedded in the URL scheme: mailto:..., http:...., etc.
RKD> Scott, I don't understand your answer. Could you clarify.
