       printcap - printer capability data base


       Printcap  is a simplified version of the termcap(5) data base used to describe line print-
       ers.  The spooling system accesses the printcap file  every  time  it  is  used,  allowing
       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 term-
       cap, 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,  -Pprinter,  to  allow  explicit
       naming of a destination printer.

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

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

       xs     num   0			like `xc' but set bits

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

       The  lpd(8)  daemon  creates  a	pipeline  of filters to process files for various printer
       types.  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
	      -f   rf	     Fortran
	      -t   tf	     troff
	      -v   vf	     raster image

       The if filter is invoked with arguments:

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

       The -c flag is passed only if the -l flag (pass control characters literally) is specified
       to lpr.	Width and length specify the page width and length (from pw and pl  respectively)
       in characters.  The -n and -h parameters specify the login name and host name of the owner
       of the job respectively.  Acct-file 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 perform-
       ing accounting.	The of is only given the width and length flags.

       All other filters are called as:

	    filter -xwidth -ylength -n login -h host acct-file

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

       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.

       Error messages generated by the line printer programs themselves (that is,  the	lp*  pro-
       grams)  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 themselves.

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