XEROX DOCUPRINT NPS GUIDE TO USING PAGE DESCRIPTION LANGUAGES 1-11
If a given page has only a Page Size specification, it is used to
identify the required medium in the media list. If no exact match is
available, the medium closest in size is used. If there is more than
one medium of the chosen size (differing in color or weight), the one
appearing first in the media list is used.
If a given page contains only a Paper Source specification, this
determines the medium for the page. The medium used is the nth
medium in the media list, where n is the tray that has been specified
in the Paper Source command. If the number of the tray specified in
the Paper Source command is greater than the number of media in
the media list, then the paper source command is ignored.
If none of three methods of specifying media is available for a given
page, then the medium specified for the previous page is used, with
two exceptions: an ExceptionPages specification is not used, and if
the page is a first page, then the first medium in the media list is used.
For duplex jobs, the medium for the front side of a given sheet is the
medium used for the sheet, regardless of the medium selected for
the back side.
PCL Output Bin command
Caution: Do not use the DocuPrint NPS Output Bin attribute when
using the PCL Output Bin command, otherwise the PCL command
will be ignored.
PCL uses the Output Bin command (<Esc>&l#G) to select an output
bin (where # is replaced by a number):
When # = 1, then the Stacker Group will be 1.
When # = 2, then the Stacker Group will be 2.
PCL Offset Registration commands
The PCL Left Offset Registration command (<Esc>&l#U) and Top
Offset Registration command (<Esc>&l#Z) are not supported when
the job is duplexed. (The # symbol is used to indicate the size of the
offset.)
The Left and Top Offset Registration commands instruct the printer
to shift the entire page image in a desired direction. Unfortunately,
the PCL specification has made the direction of the requested shift
dependent on which page-side (front or back) and in which plex
(long-edge binding or short-edge binding) the page is printed. The
PCL interpreter on DocuPrint NPS is designed to emulate the HP
LaserJet 4, a simplex-only printer. Therefore, it does not perform the
correct registration offset when plex and page-side PCL commands
are used.
The page images passed from the PCL interpreter to the DocuPrint
sequencer are images as they would appear on an HP LaserJet 4. In
addition to the page images, certain switches are passed to the
sequencer to indicate desired output behaviors. The switches can
control the plex, requested page-side, media index, number of
copies, and output bin. These switches make it possible for the
sequencer to emulate most of the behaviors of duplexing PCL
