	    [ filename ...  ]

DESCRIPTION
       Lpr  uses a spooling daemon to print the named files when facilities become available.  If
       no names appear, the standard input is assumed.

OPTIONS
       -A   The authentication type is set by the value of the AUTH environment variable.

       -B   Do filtering of job files by the filters specified by the printcap.  Combine the out-
	    put  of  the filtering operation into a single job file and then send the single file
	    to the lpd print spooler.

       -b, -l
	    either of these flags specifies a binary or literal file, and no (or  minimial)  pro-
	    cessing  is to be done by the print spooling system.  Printed using the f format fil-
	    ter (:if=... or :filter=...).

       -C class
	    Specify the job classification for use on the burst page and  to  set  the	priority.
	    Priorities	range  from  A	(lowest)  to Z (highest); the default priority is A.  For
	    example,
		 lpr -C B foo.c
	    sets the priority/class to B and the file foo.c is printed.

       -D debugoptions
	    Debugging is controlled using the -D option. This accepts a comma-separated  list  of
	    debugging settings. These settings take one of two forms: facility=value, or value to
	    set an overall default value.

       -F filterformat
	    Filter or format specification.  By default, input is assumed to a standard text file
	    and  the  f  format is used; the output device is assmed to be a simple line printer.
	    Other formats available are listed below.  Not all formats may be  available  on  all
	    printers;  see  printcap(5)  for details.  Formats are single lower case letters; the
	    following are the valid arguments for -F together with the assumed type of data.  For
	    compatibility  with previous versions of lpr, the format types can be used as options
	    themselves (i.e. by omitting the F) except where noted below, a warning may be issued
	    in such cases.

       -G   Similar to the -B option, but only processes individual files.

       -h   No banner or header for this job.

       -i indentcols
	    Indent input by indentcols.  Note that this option is not supported on all printers.

       -J jobname
	    Specify the job name to print on the burst page; defaults to the name of files in the
	    job or (STDIN) if input is from a pipe.

       -Kcopies, -#copies
	    Specify the number of copies of each file to be printed.  You may or may not get  the
	    requested  number of copies depending on the intelligence of the remote printing sys-
	    tem.

       -k   lpr normally creates a temporary file for the input read from stdin before sending it
	    to	the  remote  printer.  The -k (kut-through) option will simply copy from STDIN to
	    the destination print spooling system.  If you kill the job in the middle of creation
	    then  the  partly  transferred  file will get printed.  This option may not work with
	    very large jobs, non-LPRng spoolers, or when you have  encryption  or  authentication
	    enabled.

       -m mailTo
	    Send  mail	upon  unsuccessful  completion to user mailTo.	The mailTo value has been
	    used to do such things as specify email (user@host),  paging  (page:user@host),  both
	    (user@host,page:user@host)	and  all  sorts  of  other notifier information.  See the
	    LPRng HOWTO for details on how this is implemented.

       -P printer
	    By default, the destination printer is taken from the command line -P printer  value,
	    then the environment variables PRINTER, LPDEST, NPRINTER, NGPRINTER, then first entry
	    in the printcap information, and and finally the default_printer entry from the  con-
	    figuration file, and then the compile time default.

       -R remoteAccount
	    Specify accounting information to be used by a remote system that prints your output.

	    This parameter can be used to specify a billing code to be charged for the printing.

       -r   The  DREADED  REMOVE  AFTER  PRINTING  option.  Beware, for lpr will delete the files
	    after spooling them.  Present by demand  from  users  for  compatibility  with  other
	    Berkeley lpr implementation, but really should NOT be present.

       -T  title
	    Specify the title used by pr(1); defaults to the file name.

       -U username
	    The  -U option is used to specify a user name for the job.	This is available only to
	    ROOT or users listed in the allow_user_setting configuration option.  This	is  obvi-
	    ously a security loophole, but it is present to allow systems such as SAMBA to submit
	    jobs on behalf of users.  See Authenticated Transfers below.

       -V   Verbose mode. Additional -V flags increase verbosity.  Use debug  flags  for  extreme
	    verbosity.

       -w width
	    Specify  the  page width for printing the job.  -X path User specified filter for job
	    files.  Processing is done on the client host.  -Y Make a direct  connection  to  the
	    printer device and do not spool.

       -Z options
	    Pass the specified options to the print spooler.  Used when additional or specialized
	    information must be provided to the spooler.

       OBSOLETE OPTIONS Lower case -c, -d, -g, -n, -t, -v
	    Used to indicate: -c is data produced by cifplot(l), -d is tex(l)  (DVI  format  from
	    Stanford),	-g  is standard plot data as produced by the plot(3X) routines, -n and -t
	    is output from (device independent) troff, -v a raster image  for  devices	like  the
	    Benson Varian.  These are obsolete.  These are retained for historical compatibility,
	    but most of their functionality has been replaced by the  abilities  of  the  printer
	    support system to determine the file type and do the appropriate conversions.

       OBSOLETE OPTION -p
	    This  is  obsolete.   This	option is retained for historical compatibility, but this
	    functionality should be implemented on the client system before sending  the  job  to
	    the printer.  Use pr(1) to format the files, then print using f format.  This may not
	    be supported on the print system.

       OBSOLETE -s
	    This flag is included for compatibility with other versions of lpr.   In  these  ver-
	    sions it will create a symbolic link to the files to be printed.  Lpr now sends files
	    directly to the server and it is irrelevant.

       OBSOLETE OPTIONS -1,2,3,4fontname
	    Specify a font to be mounted on font position i for TROFF printing (Obsolete).

FILENAMES
       By default, if no filenames are specified lpr will read stdin and print it.

AUTHENTICATED TRANSFERS
       The original LPR network protocol defined in RFC1179 did not provide for  user  to  server
       authentication.	 This is now supported by LPRng.  See the LPRng support documentation for
       details on its operation and support.

COMPATIBILITY
       The LPRng version of lpr attempts to be functionaly compatible with common implementations
       of lpr.	However, there are some commands and functionality that are deliberately missing.

       -s Symbolic Links
	    (Berkeley  LPR)  This option specified that a symbolic link to the original data file
	    rather than a copy of the data file was to be used when spooling jobs.  This opens up
	    a  variety	of  security  problems,  as  well as being ineffective when printing to a
	    remote host.

THE -B, -Y, -X filter ULTRA-LIGHTWEIGHT PRINTING OPTIONS
       LPRng supports ultra-lightweight printing by eliminating the need  for  a  print  spooler.
       This  is  quite dangerous, but makes the lpr client very lightweight.  The -Y command line
       option and the :direct printcap option enables lpr to connect directly to a specified port
       or  use	a  program to send a job.  This filter also enables client side filtering,  so if
       there are any filters specified in the printcap entry they will be used.  For example:
       lpr -Y -Phost%port file1 file2 ...
	approximately equivalent to:
	  for i in file1 file2 ...; do
	    ${filter} <$i;
	 # ${filter} is filter from printcap
	  done	>host%port (TCP/IP connection)

       lpr -Y -Phost%port -X userfilter file1 file2 ...
	approximately equivalent to:
	  for i in file1 file2 ...; do
	    userfilter <$i;
	  done	>host%port (TCP/IP connection)

       Summary:
	  -P host%port	  > TCP/IP connection to host%port
	  -P /dev/lp	  > /dev/lp
	  -P '|/program'  | /program

       SPECIAL CASE
       lpr -Y -Ppr@host -X userfilter file1 file2 ...
	approximately equivalent to:
	  for i in file1 file2 ...; do
	    userfilter <$i >temp.$i;
	  done
	  lpr -Ppr@host temp.file1 temp.file2

       The -B option or the :lpr_bounce is used to filter and make a single file out of a set  of
       print files and then forward them.
	      lpr -B -Ppr@host
		approximately equivalent to:
		 lpr -Y -P/tmp/tempfile file1 file2 ...
		 lpr -Ppr@host /tmp/tempfile

       You can also use a printcap entry and the :direct options.
	      Printcap:
		 lp:direct:lp=h14%9100:remote_support=R
	      lpr -Plp file1 file2
		 Same as:
	      lpr -Plp -Y -Ph14%9100 file1 file2

       The  :remote_support  option is used to prevent the lpq and lpc program from attempting to
       send jobs to the device.

ENVIRONMENT
       By default, the destination printer is taken from the command line -P printer value,  then
       the  environment  variables  PRINTER, LPDEST, NPRINTER, NGPRINTER, then first entry in the
       printcap information, and and finally the default_printer  entry  from  the  configuration
       file, and then the compile time default.

EXIT STATUS
       The following exit values are returned:

       zero(0)       Successful completion.

       non-zero (!=0) An error occurred.

PRINTCAP INFORMATION
       The printer names and other information is obtained by using a printcap file or some other
       database.  The ${HOME}/.printcap file can be used to specify user level options	and  con-
       figuration information.	See printcap(5) for more information.

FILES
       The  files used by LPRng are set by values in the printer configuration file.  The follow-
       ing are a commonly used set of default values.
       /etc/lpd.conf				    LPRng configuration file
       ${HOME}/.printcap			    user printer description file
       /etc/printcap				    printer description file
       /etc/lpd.perms				    permissions
       /var/run/lpd				    lock file for queue control
       /var/spool/lpd				    spool directories
       /var/spool/lpd/QUEUE/control		    queue control
       /var/spool/lpd/QUEUE/log 		    trace or debug log file
       /var/spool/lpd/QUEUE/acct		    accounting file
       /var/spool/lpd/QUEUE/status		    status file

DIAGNOSTICS
       Most of the diagnostics are self explanatory.
       If you are puzzled over the exact cause of failure,
       set the debugging level on (-D5) and run again.
       The debugging information will
       help you to pinpoint the exact cause of failure.
