NetBSD 6.1.5 - man page for printcap (netbsd section 5)

PRINTCAP(5)			     BSD File Formats Manual			      PRINTCAP(5)

     printcap -- printer capability data base


     The printcap data base is a simplified version of the termcap(5) data base used to describe
     line printers.  The spooling system accesses the printcap file every time it is used, allow-
     ing dynamic addition and deletion of printers.  Each entry in the data base is used to
     describe one printer.  This data base may not be substituted for, as is possible for
     termcap(5), because it may allow accounting to be bypassed.

     The default printer is normally lp, though the environment variable PRINTER may be used to
     override this.  Each spooling utility supports an option, -P printer, to allow explicit nam-
     ing of a destination printer.

     Refer to the 4.3 BSD Line Printer Spooler Manual for a complete discussion on how to set up
     the database for a given printer.

     Refer to termcap(5) for a description of the file layout.

     If the local line printer driver supports indentation, the daemon must understand how to
     invoke it.

     If a printer is specified via lp (either local or remote), the lpd(8) daemon creates a pipe-
     line of filters to process files for various printer types.  The pipeline is not set up for
     remote printers specified via rm unless the local host is the same as the remote printer
     host given.  The filters selected depend on the flags passed to lpr(1).  The pipeline set up

	   p	   pr | if regular text + pr(1)
	   none    if	   regular text
	   c	   cf	   cifplot
	   d	   df	   DVI (tex)
	   g	   gf	   plot(3)
	   n	   nf	   ditroff
	   o	   pf	   PostScript
	   f	   rf	   Fortran
	   t	   tf	   troff
	   v	   vf	   raster image

     The if filter is invoked with arguments:

	   if [-c] -wwidth -llength -iindent -n login [-j jobname] -h host acct-file

     The -c flag is passed only if the -l flag (pass control characters literally) is specified
     to lpr(1).  The width and length specify the page width and length (from pw and pl respec-
     tively) in characters.  The -n and -h parameters specify the login name and host name of the
     owner of the job respectively.  The -j parameter is optional and specifies the name of the
     print job if available.  The acct-file option is passed from the af printcap entry.

     If no if is specified, of is used instead, with the distinction that of is opened only once,
     while if is opened for every individual job.  Thus, if is better suited to performing
     accounting.  The of is only given the width and length flags.

     All other filters are called as:

	   filter -xwidth -ylength -n login [-j jobname] -h host acct-file

     where width and length are represented in pixels, specified by the px and py entries respec-

     All filters take stdin as the file, stdout as the printer, may log either to stderr or using
     syslog(3), and must not ignore SIGINT.

     Filters can communicate errors to lpd by their exit code and by modifying the mode of the
     spool lock file as follows:
	   Exit code  Description
	   0	      Success.
	   1	      An attempt is made to reprint the job and mail is sent if it fails.
	   2	      lpd(8) silently discards the job.
	   n	      lpd(8) discards the job and mail is sent.
	   lock code  Description
	   u+x	      Stop printing and leave queue disabled (S_IXUSR).
	   o+x	      Rebuild the queue (S_IXOTH).

     Error messages generated by the line printer programs themselves (that is, the lp* programs)
     are logged by syslog(3) using the LPR facility.  Messages printed on stderr of one of the
     filters are sent to the corresponding lf file.  The filters may, of course, use syslog(3)

     Error messages sent to the console have a carriage return and a line feed appended to them,
     rather than just a line feed.

     4.3 BSD Line Printer Spooler Manual.

     The sh flag is a function of the spooler with the locally attached printer, and so has no
     effect when used with rm.	NetBSD never adds a burst page when used as a remote spooler.  To
     suppress the burst page for other systems or dedicated devices, refer to the documentation
     for those systems or devices.

     The printcap file format appeared in 4.2BSD.
