printcap
data base is used to describe line
printers. The spooling system accesses the 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.
The default printer is normally lp, though the
environment variable PRINTER
may be used to override
this. Each spooling utility supports an option, -P
printer, to allow explicit naming of a destination
printer.
Refer to the 4.3 BSD Line Printer Spooler Manual for a complete discussion on how to set up the database for a given printer.

If the local line printer driver supports indentation, the daemon must understand how to invoke it.

The if filter is invoked with arguments:
if
[-c
]
-w
width
-l
length
-i
indent
-n
login
[-j
jobname]
-h
host acct-fileThe -c
flag is passed only if the
-l
flag (pass control characters literally) is
specified to lpr(1). The
width and length specify the
page width and length (from pw
and
pl
respectively) in characters. The
-n
and -h
parameters specify
the login name and host name of the owner of the job respectively. The
-j
parameter is optional and specifies the name of
the print job if available. The acct-file option is
passed from the af
printcap
entry.
If no if
is specified,
of
is used instead, with the distinction that
of
is opened only once, while
if
is opened for every individual job. Thus,
if
is better suited to performing accounting. The
of
is only given the width and
length flags.
All other filters are called as:
filter
-x
width
-y
length
-n
login
[-j
jobname]
-h
host acct-filewhere width and length
are represented in pixels, specified by the px
and
py
entries respectively.
All filters take stdin as the file,
stdout as the printer, may log either to
stderr or using
syslog(3), and must not ignore
SIGINT
.
Filters can communicate errors to lpd by their exit code and by modifying the mode of the spool lock file as follows:
LPR
facility. Messages printed on
stderr of one of the filters are sent to the corresponding
lf
file. The filters may, of course, use
syslog(3) themselves.
Error messages sent to the console have a carriage return and a line feed appended to them, rather than just a line feed.
