10 GETTING TO KNOW THE M208: Overview of Print Server Architecture
Summary
When you are doing a print setup, you must direct print jobs to a particular destination
which is mapped to an I/O port to which the printer(s) is attached. The destination’s
associated model is then used for any extra processing of the data, if required. Each
I/O port has an internal queuing mechanism that automatically queues print jobs on a
first-come, first-serve basis.
For more information on I/O ports, destinations, and models, please see M208 INTER-
NAL ARCHITECTURE on page 89.

This example follows a print job sent to destination
d1prn.
d1prn
is associated with model
m1
and the I/O port
prn
.
When the data is passed through the associated model, any job
processing specified by the model is performed on the data.
If no additional processing is specified, the data is passed
through to the I/O port untouched.
