In the P2600 main document there is a very high level generic architecture
of a Hardcopy Device which help to provide a common base for discussion.
Although I am not proposing that we specifically use the P2600 generic
architecture; would it be helpful to the PWG members and the those who will
use the specifications to create the generic MFD architecture, labeling and
general nomenclature to be used of all related specifications. As Bill
points out the terms depend upon our perspective and, thus, can vary.
