     NAME
          psbanner, pscomm, psinterface,  psrv,  pstext  -  TRANSCRIPT
          spooler filters for POSTSCRIPT printers

     SYNOPSIS
          /usr/lib/ps/psbanner
          /usr/lib/ps/pscomm
          /usr/lib/ps/psinterface
          /usr/lib/ps/psrv
          /usr/lib/ps/pstext

     DESCRIPTION
          These are the low-level TRANSCRIPT interface filters for use
          by the System V line printer spooling system.  The psinter-
          face shell script is a printer interface program that may be
          supplied to lpadmin.  The options are as specified in the
          A/UX Local System Administration.  This shell script sources
          a printer-specific shell script named transcript/printer.opt
          below the current working directory (the lp spooling direc-
          tory) which may do additional printer-specific processing
          (for example, specify no page reversal).  psinterface is
          responsible for the complete processing of the print job.
          If job banner break pages are enabled for this printer (and
          requested for this job), psinterface will invoke psbanner to
          format a banner break page.  psinterface also distinguishes
          between text files (which get formatted) and POSTSCRIPT
          print files.  If the input to psinterface does not begin
          with the POSTSCRIPT ``magic number'' (the first two charac-
          ters being %!), psinterface will invoke pstext to create a
          listing of the file.  If the first bytes of the input file
          are %!PS-Adobe-, and if the printer options so specify,
          psinterface will also page-reverse the file (with the psrv
          filter) before printing.  psinterface currently recognizes
          three TRANSCRIPT-specific spooling options (presented to lp
          with the -o flag option): the h flag option suppresses the
          printing of a banner break page, the r flag option
          suppresses page reversal, and the m flag option causes psin-
          terface to send any stream output from the execution of the
          user's POSTSCRIPT print file back to the user as mail.

          The program pscomm is the lowest level filter.  It manages
          communication with the printer, error handling, status re-
          porting, etc.  psinterface and pscomm manage a printer log
          file named transcript/printer-log (under the lp spooling
          directory).  This file contains a log of each job processed,
          as well as any error output from the printer.  In particu-
          lar, it contains messages regarding paper-out, paper-jams,
          and so forth.  Doing a tail on this file will help determine
          the printer's status.
