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 output 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) processing is to be done by the print spooling
            system.  Printed using the f format filter (: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 system.

       -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 configuration
            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 obviously 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 versions 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 configuration information.  See
       printcap(5) for more information.

FILES
       The files used by LPRng are set by values in the printer configuration
       file.  The following are a commonly used set of default values.
       /etc/LPRng/lpd.conf                          LPRng configuration file
       ${HOME}/.printcap                            user printer description file
       /etc/printcap                                printer description file
       /etc/LPRng/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.
