1-8 XEROX DOCUPRINT NPS GUIDE TO USING PAGE DESCRIPTION LANGUAGES
*DocuPrint implements the Paper Source command by
corresponding the number specified in the command to the
correlating media in the media list of the Media document attribute.
Therefore, the "Feed from upper tray" command specifies the first
media in a media list in the document attribute and the "Feed from
lower tray" command specifies the fourth media in a media list in the
document attribute. Refer to the “PCL Paper Source command”
section for more information.
For information on mixed plex jobs for Models 96, 4635, and 180,
see the chapter “Mixed plex applications” in the Guide to Managing
Print Jobs.
PCL Job Separation command
PCL uses the Job Separation command (<ESC>&l1T) to separate
distinct portions of the output by offsetting a set of sheets in the
output from a succeeding set of sheets.
There is a short description of the PCL Job Separation command in
the HP documentation. This command is only supported on the HP
LaserJet IIISi. HP recommends that the Job Separation command be
included at the end of each job. There is no mention of possible side
effects when this practice is not followed.
This PCL Job Separation command description is based on the
printing behavior observed on the HP LaserJet IIISi. Job Separation
toggles the output tray offset. It is primarily a printer hardware
function. There were no observed page processing effects.
The PCL Job Separation command has these major features:
• The Job Separation command operates independent of all
other PCL commands. This command is the only PCL
command that changes the output tray offset.
• The Job Separation command toggles the output tray offset.
The output tray offset is switched between two positions. This
command does not set the output tray offset to a specific
position.
• The Job Separation command sends a hardware command to
toggle the output tray offset that is executed immediately.
• The Job Separation command takes effect on the current page
that is being processed. It will be observed when this page is
ejected.
• The output tray offset is retained between print jobs. This offset
consistency cannot be guaranteed since there are ways to
change the output tray offset between print jobs.
When a PCL Job Separation command is encountered on a page,
DocuPrint NPS will offset that page from the previous page. If the job
is printed duplex and the command is encountered on the backside
of the page, DocuPrint NPS will not offset the current page. In this
case, the next page will be offset. There are other conditions that
result in different sets of paper being offset in the output tray.
The DocuPrint NPS currently provides consistent support of the PCL
Job Separation command when it appears at the beginning of the
print job section that should be offset. There are several
recommendations to consider for the use of the PCL Job Separation
command in DocuPrint NPS printing environments:
