    Hi Michael,

    As far as I know, IPP support is slowly working its way into network printer
    interfaces for the label printing niche (both impact and direct
    thermal/thermal transfer print technologies) and into some of the dot matrix
    printer NIC's as well.

    These types of printers do not support the same document formats as the
    inkjet and laser technology based printers.

    If IPP were to become involved with specifying document formats, I think it
    would be a good idea to create a separate IPP document formats track with
    its own RFC or PWG based specification that could be referenced by the ippv2
    documents.

    Best Regards,

    /Paul
