#    MODULE:
#      The PostScriptFilter -    The NUC Client Network Printer NeXT2_0
#                    lpd spooler PostScript filter program.
#                    Component of the NUC PCLIENT Services.
#
#    ABSTRACT:
#      The PostScriptFilter.c contains the NeXT platform dependent
#      printjob() PostScript filter interface program, which services all
#      NetWare PostScript Printers in behalf of printjob() in the lpd(8)
#      spooler.  This shell script establishes a pipe which reads from the
#      print file mapped onto STDIN, any necessary print filter program,
#      and the printjob_nucps(1) shell backend command.  The printjob()
#      function linked into the lpd(8), PrintPanel(GUI) programs calls
#      this program to spool print files to NetWare QMS print queues.
#
#    NOTE:
#      The print system model implemented by Novell on NeXT platforms
#      follows the file system model for dependent file systems.  The NetWare
#      NCP Printer Service Class is represented by the following dependent
#      shell commands:
#        PostScriptFilter    (This Shell Script)
#        independentFilter    (Parent Shell Script)
#        displayq_nucps        (Related Shell Script)
#        printjob_nucps        (This Scripts PIPE Child Program)
#        rmjob_nucps        (Related Program)

#    -h hostName        - Name of host print file originated on.
#    -iChIndent        - Left margin indentation in characters. Used
#                  with ASCII files.
#    -lChLength        - Length of page in lines. Used with
#                  ASCII files.
#    -n userName        - Name of User who spooled the file.
#    -p printerName        - Name of printer known by on NeXT work station.
#    -wChWidth        - Width of page in characters. Used with
#                  ASCII files.
#    -xPxWidth        - Width of page in pixels. Used for Bit Maps.

#    -R resolution        - Resolution in Dots Per Inch of print
#                  print resolution desired.
#
# INPUT
#    None.
#
# OUTPUT
#    Successfull    - Silently exits back to printjob() in parent lpd(8)
#    Failure        - Abort message formatted and displayed on
#              STDOUT.
#
# DESCRIPTION
#    The PostScriptFilter sets up the unspooling PIPE of a file being
#    scheduled for lpd[printjob.o] to a remote NetWare PostScript printer. It
#    is invoked by its filter name in printcap(5)/netinfo(5).  This shell
#    script sets up a pipe to its printjob_nucps(1) NetWare handler with the
#    appropriate filter pushed.  All filtering is done on the NeXT work
#    station prior to spooling it over the wire.
#
#    Note:
#        All names are hard linked to the same shell script for
#        servicing.  The called name indicates the filter setup
#        model to be used.
