I have a real problem with this because 99.99% of the printing
done today does not provide this kind a functionality. Late
binding is a concept that exists in none of the major operating
systems and only in certain packages like Dazel. Additionally,
while the protocol may support this type of function, it is not
in our area to tell application writers what functions are to be
exposed to the user. We can define a model and a protocol
mapping that is neutral as to the source of the job but beyond
that it is really up to the implementors of the user interface,
the print server and the printer as to whether the things you
ask for are implemented or every possible.
I really think this is more "fat" being added to IPP. As we
discussed briefly on last week's conference call, this is all
becoming way to heavy. We really need to start thinking about
a real minimal implementation requirement with functionality
like the Microsoft proposal with (I hate to say this so you IPDS
guys cover your ears) "towers" of functionality that can be
negotiated between the submitter and the server. We have got
to cut this down to what is really necessary and focus on getting
that done and implemented ASAP!!!

Subject: IPP> REQ - ISSUE - Add a requirement that printing files have same
capabilites as printing from an application
One of the requirements that we should add relates the functionality that
a user has available over a file or document that has already been produced
(usually be a different user) as compared with the functionality that
a user has when printing from an application that generates the PDL on
the fly (using the platform's GDI and printer driver).
The web has shifted the printing paradigm from mainly printing from current
running applications to a more balanced approach between two printing
paradigms: printing from the application and printing from a previously
produced document or file.
We need to be striving to provide the same functionality to the end-user
for both printing paradigms with IPP.
So I suggest adding a requirement something like:
IPP shall provide the same functionality to the end-user for print
time choices of stored documents as the end-user has for printing
directly from an application.
For example, the user can choose number of copies, two-sided, stapling,
number-up, and page ranges, etc. whether printing from the application
that has the entire document or printing from a file or document that
has been stored on the web or in a document repository.
Commments?
