.SH NAME
printcap \- printer capability data base
.SH SYNOPSIS
/etc/printcap
.SH DESCRIPTION
.I printcap
is a simplified version of the
.IR termcap (5)
data base
used to describe line printers. The spooling system accesses the
.I printcap
file every time it is used, allowing dynamic
addition and deletion of printers. Each entry in the data base
is used to describe one printer. This data base may not be
substituted for, as is possible for
.IR termcap ,
because it may allow accounting to be bypassed.
.PP
The default printer is normally
.IR lp ,
though the environment variable
.I PRINTER
may be used to override this. Each spooling utility supports an option,
.BI \-P printer,
to allow explicit naming of a destination printer.
.SH CAPABILITIES
Refer to
.I termcap
for a description of the file layout.

\fBName Type Default Description\fR
sd str ``/usr/spool/lpd" spool directory
lo str ``lock" name of lock file
st str ``status" status file name
dn str ``/usr/lib/lpd" spooling daemon's path name
lf str ``/dev/console" error logging file name
lp str ``/dev/lp" device name to open for output
br num none if lp is a tty, set the baud rate (ioctl call)
fc num 0 if lp is a tty, clear flag bits (sgtty.h)
fs num 0 like `fc' but set bits
rm str NULL machine name for remote printer
rl str ``/usr/lib/rlpr" remote lpr started by local daemon
bd str ``/usr/ucb" bin directory of lpr, lpq, lprm
rp str NULL remote printer name argument (lp by default)
mx num 1000 maximum file size (in BUFSIZ blocks)
of str NULL name of output filtering program
af str NULL name of accounting file
ff str ``\ef" string to send for a form feed
tr str NULL trailer. string to print when queue empties
pw num 132 page width

sb bool false short banner (one line only)
sh bool false suppress printing of burst page header

.PP
Output is sent to the remote machine if line printer device is null.
For expamble, the following line would send output to the machine
`ucbvax'.

.PP
The `br', `fc', and `fs' entries are used to change tty characteristics
(see
.IR tty (4)).
The `fc' and `fs' entries only set or clear the specified bits in the
.I g_flags
field; the rest are unchanged.
.PP
Error messages sent to the console have a carriage return and a line
feed appended to them, rather than just a line feed.
.PP
If the local line printer driver supports indentation, the daemon
must understand how to invoke it.
