    Hello Emile,

    No, IPP can't do what you describe below. IPP uses an HTTP transport,
    but ONLY exchanges 'application/ipp' MIME binary-encoded messages.

    The IEEE/ISTO PWG (Printer Working Group) is rapidly completing a
    new Web Services printing interface, which uses WSDL-defined SOAP
    operations, exchanging XML text-encoded messages, called Printing
    Systems Interface (PSI).

    The PSI effort above is using the XML schema definitions for the
    entire semantic content of IPP being developed in the parallel
    IEEE/ISTO PWG Semantic Model effort (nearing completion for
    version 1.0).

    Even if you don't want to use WSDL/SOAP infrastructure, you might
    take advantage of the PWG Semantic Model definitions of all the
    IPP semantic elements (media, finishing, etc.) in your forms-based
    printing solution.

    To learn more about these IEEE/ISTO PWG efforts, please visit the
    PWG home page at http://www.pwg.org

    we're developing some software that requires the user to fill out a form
    (generated on the server) before the printjob can be submitted,
    something like


    request print job --->
             <---- Form to be filled in (XML-based)
    send postscript + form ---->
             <----- Acknowledge job


    request print job --->
             <---- Form to be filled in (XML-based)
    send postscript + form ---->
             <----- PDF preview
    Acknowledge preview --->
             <----- Acknowledge job

    Is this at all possible using IPP? We currently have a proprietary
    solution over http with active agents on buth sides, we'd like to
    simplify stuff on the user side.
