.Sh DESCRIPTION
|
|
.Nm Lp
|
|
is a front-end to the print spooler as required by the
|
|
.St -p1003.2
|
|
specification. It effectively invokes
|
|
.Xr lpr 1
|
|
with the proper set of arguments.
|
|
|
|
It generally prints the named files on the destination printer.
|
|
.Pp
|
|
Option
|
|
.Fl c
|
|
makes the
|
|
.Nm
|
|
command exit only after further access to any of the input files is no
|
|
longer required. The application can then safely delete or modify the
|
|
files without affecting the output operation.
|
|
|
|
To specify a particular printer, option
|
|
.Fl d Ar dest
|
|
can be used. If no
|
|
.Fl d
|
|
is provided on the command line, the contents of the environmental
|
|
variables
|
|
.Ev LPDEST
|
|
or
|
|
.Ev PRINTER
|
|
.Pq with this precedence
|
|
are taken as the destination printer.
|
|
|
|
Option
|
|
.Fl n Ar num
|
|
can be used to specify that
|
|
.Ar num
|
|
copies of each of the named files shall be printed.
|
|
|
|
.Sh ENVIRONMENT
|
|
As described above, the variables
|
|
.Ev LPDEST
|
|
and
|
|
.Ev PRINTER
|
|
are examined to select the destination printer.

.Sh STANDARDS
|
|
The
|
|
.Nm lp
|
|
command is expected to comply with the
|
|
.St -p1003.2
|
|
specification.
|
|
.Sh AUTHOR
|
|
This implementation of the
|
|
.Nm
|
|
command has been written by
|
|
.if t J\(:org Wunsch.
|
|
.if n Joerg Wunsch.
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
command inherits several bugs from the utilities invoked, namely it
|
|
requires any option separated from its argument by a whitespace
|
|
since the getopts implementation of
|
|
.Xr sh 1
|
|
is broken, and it does not honour dashes as input file names
|
|
.Pq meant to use standard input
|
|
since
|
|
.Xr lpr 1
|
|
ignores them.
|
|
|
|
The
|
|
.St -p1003.2
|
|
specification does not provide any means to print non-text files. It
|
|
rather requires the files to be printed to be text files limited to
|
|
reasonable line lengths and printable characters.
