    It might be a good addition in order to get agreement on the name for the
    device default setting when the client wants (or needs) to explicitly convey
    to the device that the client wants the device to use its default setting.
    If the user is talking to the driver (on the client) then this value would
    also cause the driver NOT to insert any default value of its own (or to find
    out from the device or PPD/GPD/UPDF what the devices default value was and
    insert that value explicitly). However, note that in other job submission
    protocols, such as IPP, the client merely omits the attribute and the
    Printer applies its default value for any omitted attributes.
     
    So if we did add such a 'device-setting' name value, we should add the words
    that the use of the 'device-setting' value depends on the protocol and may
    not be appropriate for some protocols. Since the value applies to all
    fields in the Media Standardized Names standard, we could also indicate the
    'device-setting' value as a RECOMMEND value when it is necessary to indicate
    that a default value is to be used.
     
    BTW, 'device-setting' is the value that UPnP uses, since the UPnP protocol
    requires that the client send all attributes in every job submission.

    Subject: IPP> use printer setting

    More a question than a request:
    Do we want to add a predefined keyword like
        'device-setting'
    to all four lists?
     
    I can well imagine that a driver/client is intending to let the device
    decide where to pull the media from.
    This would represent the typical 'auto' setting.
     
    While I consider it very unusual for media sizes (we would add it more for
    consistency), I can well imagine the use of it for the other media
    attributes.
    This is usual behavior of today's drivers.
