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.

SAI> I agree that the name service should NOT have relatively dynamic

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> is to walk down the hallway and look at the printer.

<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.
