AGILE 5250 OPTIMA User’s Guide and ReferencePage A-4
These separate addresses appear to the system as two logical printers,
although they can share a single Xerox printer. The OPTIMA
automatically holds data from one address when the other address is using
the printer, in the same way that it queues an alternate host data stream
from a PC.
When using separate addresses for conflict avoidance, one address is used
to print only XES- or XPPM-formatted documents, and the other address is
used to print only SCS-formatted (system) documents. This method
eliminates both the need for the OPTIMA to change modes of operation
and the need for nonstandard printable sequences in the data stream to
trigger mode changes.
The drawback of this method is that FF suppression must be constantly on
or off, and it cannot be changed dynamically. Using this method, either all
or none of the form feeds sent by the system go to the printer. See the
sections Auto PFS Suppression and Auto FF Termination for some
possible to this problem. Also, refer to the next section for another method
of initiating and terminating PFS and FF suppression modes that does not
suffer from this limitation.
Delimiting XES Jobs
The OPTIMA provides two different methods of initiating and terminating
PFS and FF suppression based upon printable trigger sequences.
Automatic PFS/FF suppression uses the natural format of an XES mode
job to automatically turn on PFS and/or FF suppression at the beginning
of an XES command data stream, and turn the suppression off at the end of
the XES command data stream.
For XES jobs that do not conform to conventions, and for compatibility
with existing applications and documents, the OPTIMA also supports
Logical Not (¬) commands that can be used to independently initiate and
terminate PFS and FF suppression modes.
Well-Formed XES Jobs
The XES command set provides several commands that are used to declare
the beginning of a print job. Each of these commands declares the
beginning of a different type of job. The XES command set also includes a
command to end the print job.
This document uses the term well-formed to refer to an XES print
job that uses XES commands to delimit the beginning and end of a
print job.
