XES command generation
This chapter describes how to create and insert Xerox Escape Sequence 
(XES) control commands into the print data stream.
Using XES control commands
The generation of XES commands is restricted, depending on whether 
Monitor Queue is in *JOB or *PAGE file processing mode. Use one of 
these methods for generating XES commands:
None
You can use the Always generate (ALWAYS) Monitor Queue parameter 
to print a job without inserting any XES control commands that affect 
document formatting.
Indirect method
In the Indirect method, Monitor Queue maps printer file parameters to 
XES control commands and inserts the commands into the print data 
stream. The spool file is then released to the printer writer.
Direct method
In the Direct method, you first create a file of XES control commands, 
called an XES packet. The system inserts these XES control commands 
into the data stream before releasing the spool file to the printer writer.
Combined method
In the Combined method, you create a file of XES control commands, then 
Monitor Queue maps the spool file attributes to these commands. 
XDPE/400 inserts both sets of XES control commands into the print data 
stream before releasing the spool file to the printer writer.
