NAME

lpr − off-line print

SYNOPSIS

lpr [ −Pprinter ] [ −#num ] [ −C class ] [ −J job ] [ −T title ]
[ −i [ numcols ] ] [ −1234 font ] [ −wnum ] [ −pltndgvcfrmhs ] [ name ... ]

DESCRIPTION

lpr uses a spooling daemon to print the named files when facilities become available.  If no names appear, the standard input is assumed.  The −P option may be used to force output to a specific printer.  Normally, the default printer is used (site dependent), or the value of the environment variable PRINTER is used. 

The following single-letter options are used to notify the line printer spooler that the files are not standard text files. The spooling daemon will use the appropriate filters to print the data accordingly. 

−pUse pr(1) to format the files.

−lUse a filter that allows control characters to be printed and suppresses page breaks. 

−tThe files are assumed to contain data from troff(1) (old troff; C/A/T phototypesetter commands). 

−nThe files are assumed to contain data from ditroff (new troff; device-independent troff). 

−dThe files are assumed to contain data from tex(l) (DVI format from Stanford). 

−gThe files are assumed to contain standard plot data as produced by the plot(3X) routines.

−vThe files are assumed to contain a raster image for devices like the Benson-Varian. 

−cThe files are assumed to contain data in a CIF format. 

−fUse a filter that interprets the first character of each line as a standard FORTRAN carriage control character. 

The remaining single-letter options have the following meanings:

−rRemove the file upon completion of spooling or upon completion of printing (with the −s option). 

−mSend mail upon completion. 

−hSuppress the printing of the burst page. 

−sUse symbolic links if available.  Usually files are copied to the spool directory. 

The −C option takes the following argument as a job classification for use on the burst page.  For example:

lpr −C EECS foo.c

causes the system name (the name returned by hostname(1)) to be replaced on the burst page by EECS and the file foo.c to be printed. 

The −J option takes its argument as the job name to print on the burst page.  Normally, the first file’s name is used. 

The −T option uses its argument as the title used by pr(1) instead of the file name.

To get multiple copies of output, use the −#num option, where num is the number of copies desired of each file named.  For example,

lpr −#3 foo.c bar.c more.c

would result in three copies of the file foo.c, followed by three copies of the file bar.c, etc.  On the other hand,

cat foo.c bar.c more.c | lpr −#3

will give three copies of the concatenation of the files. 

The −i option causes the output to be indented. If the next argument is numeric, it is used as the number of blanks to be printed before each line; otherwise, eight characters are printed. 

The −w option takes the immediately following number to be the page width for pr.

The −s option will use symlink(2) if available to link data files rather than trying to copy them so large files can be printed.  This means the files should not be modified or removed until they have been printed.

The option −1234 specifies a font to be mounted on font position I.  The daemon will construct a .railmag file referencing /usr/lib/vfont/name.size.

DIAGNOSTICS

If you try to spool too large a file, it will be truncated.  lpr will object to printing binary files.  If a user other than root prints a file and spooling is disabled, lpr will print a message saying so and will not put jobs in the queue.  If a connection to lpd on the local machine cannot be made, lpr will say that the daemon cannot be started.  Diagnostics regarding missing spool files needed by lpd may be printed in the daemon’s log file. 

BUGS

Fonts for troff and tex reside on the machine to which the printer is attached. It is currently not possible to use local font libraries.
