Destinations/Queues
For every I/O port on the Ethernet Interface, there is at least one
pre-defined logical print queue or destination to accept print jobs
destined for it. This includes print job that is sent directly to the I/O
port, such as port 9100. These queue or destination names are pre-
defined but can be changed by the user.
Models
For every destination or queue, there is a pre-defined model
associated with it. The model defines how the print job will be
processed as it passes through to the printer. Models are a set of
mini filters that can be used to modify the print data stream. The
functions available for each model are as follows:
1. Insert carriage return after line feed
2. Insert a banner page before or after each print job
3. Insert header strings to
• Print in landscape mode
• Print in portrait mode
4. Insert trailer strings to
• Reset the printer once the print job completes
• Force the end of the job
• Perform a form feed at the end of the data
