        The event which causes the printer to enter the waiting state
        is product specific.  If the printer is not waiting for manually
        fed media, it may switch from an empty subunit to a different
        subunit without waiting for the time-out to expire.

        A value of (-1) implies 'other' or 'infinite' which translates
        to 'wait forever'.  The action which causes printing to continue
        is product specific.  A value of (-2) implies 'unknown'."

-- The Marker Group

-- A marker is the mechanism that produces marks on the print

-- represented by the Marker Group in the model.  A printer can
-- contain one or more marking mechanisms.  Some examples of
-- multiple marker sub-units are: a printer
-- with separate markers for normal and magnetic ink or an
-- imagesetter that can output to both a proofing device and
-- final film.  Each marking device can have its own set of
-- characteristics associated with it, such as marking technology

-- The Print Job Delivery Channel Group
--
-- Print Job Delivery Channels are independent sources of print
-- data.  Here, print data is the term used for the information
-- that is used to construct printed pages and may have both data
-- and control aspects.  The output of a channel is in a form
-- suitable for input to one of the interpreters as a
-- stream.  A channel may be independently enabled (allowing
-- print data to flow) or disabled (stopping the flow of
-- print data).  A printer may have one or more channels.
--
-- The Print Job Delivery Channel table describes the
-- capabilities of the printer and not what is currently being
-- performed by the printer
--
-- Basically, the print job delivery channel abstraction
-- describes the final processing step of getting the print data
-- to an interpreter.  It might include some level of
-- decompression or decoding of print stream data.
-- channel.  All of these aspects are hidden in the channel
-- abstraction.
--
-- There are many kinds of print job delivery channels; some of
-- which are based on networks and others which are not.  For
-- example, a channel can be a serial (or parallel) connection;
-- it can be a service, such as the UNIX Line Printer Daemon
-- (LPD), offering services over a network connection; or
-- it could be a disk drive into which a floppy disk with
-- the print data is inserted.  Each print job delivery channel is
-- identified by the electronic path and/or service protocol
-- used to deliver print data to a print data interpreter.
--
-- Channel example                   Implementation
--
-- serial port channel            bi-directional data channel

-- parallel port channel          often uni-directional channel
-- IEEE 1284 port channel         bi-directional channel
-- SCSI port channel              bi-directional
-- Apple PAP channel              may be based on LocalTalk,
--                                Ethernet or Tokentalk
-- LPD Server channel             TCP/IP based, port 515
-- Netware Remote Printer         SPX/IPX based channel
-- Netware Print Server           SPX/IPX based channel
--
-- It is easy to note that this is a mixed bag.  There are
-- some physical connections over which no (or very meager)
-- protocols are run (e.g., the serial or old parallel ports)
-- and there are services which often have elaborate
-- protocols that run over a number of protocol stacks.  In
-- the end, what is important is the delivery of print data
-- through the channel.
--
-- The print job delivery channel sub-units are represented by
-- the Print Job Delivery Channel Group in the Model.  It has a
-- current print job control language, which can be used to
-- specify which interpreter is to be used for the print data and
-- to query and change environment variables used by the
-- interpreters (and Management Applications).  There is also a
-- default interpreter that is to be used if an interpreter is
-- not explicitly specified using the Control Language.

-- The first seven items in the Print Job Delivery Channel Table
-- define the "channel" itself.  A channel typically depends on
-- other protocols and interfaces to provide the data that flows
-- through the channel.
--
-- Control of a print job delivery channel is largely limited to
-- enabling or disabling the entire channel itself.  It is likely
-- that more control of the process of accessing print data
-- will be needed over time.  Thus, the ChannelType will
-- allow type-specific data to be associated with each
-- channel (using ChannelType specific groups in a fashion
-- analogous to the media specific MIBs that are associated
-- with the IANAIfType in the Interfaces Table).  As a first
-- step in this direction, each channel will identify the
-- underlying Interface on which it is based.  This is the
-- eighth object in each row of the table.
