Peter, you have spotted a good set of issues. Please see my suggested
replies inserted in your text below. But remember my earlier comments
about having details in the scenarios, which we feel are important,
but which are either outside the scope of IPP or will be addressed in
later IPP versions. We should insert notes to that effect in the
scenarios document, once we have nailed down exactly what goes into

We might consider including a single value for printing single-sided on
normal sized white paper, or leave it alltogether. I would not like to
have the complexity of price negotition depending on media etc. as part
of IPP V1.0

Could potentially be done by matching postal area codes, which will probably
work in a number of countries, but not all. Complexity that we might better
stay away from in IPP V1.0.

I consider this to be an implementation matter, that would be outside the scope
of IPP, but it could still stay in the scenarios to show the whole picture

We need a way of indicating notification methods - the ones available at the
printer/print server, and the one desired by the print request submitter.
So far, we have only spoken about email (BTW there is a new set of Notification
Services recently defined by the IETF email folks, but these is not yet widely
implemented), other methods may become available later (such as push from a

NO. Does anybody consider these to be end-user functions? So far I have only
heard them being discussed as operator functions.
