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 environ-
            ment variable.

       -B   Do filtering of job files by the filters specified by  the  print-
            cap.   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 sys-
            tem.  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  (high-
            est); 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  let-
            ters;  the  following are the valid arguments for -F together with
            the assumed type of data.  For compatibility  with  previous  ver-
            sions  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.

LPR(1)                                                     LPR(1)


       -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 sup-
            ported 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  cre-
            ation  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  infor-
            mation.   See  the  LPRng  HOWTO for details on how this is imple-
            mented.

       -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.

LPR(1)                                                     LPR(1)


       -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  speci-
            fied 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 addi-
            tional 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 inde-
            pendent) troff, -v a raster image for devices like the Benson Var-
            ian.   These are obsolete.  These are retained for historical com-
            patibility, 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 compati-
            bility, 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.



LPRng                      LPRng-3.9.0                          3





LPR(1)                                                     LPR(1)


       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 ...



LPRng                      LPRng-3.9.0                          4





LPR(1)                                                     LPR(1)


                 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  print-
       cap(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
